/**
  Erases and initializes a firmware volume block.

  The EraseBlocks() function erases one or more blocks as denoted
  by the variable argument list. The entire parameter list of
  blocks must be verified before erasing any blocks. If a block is
  requested that does not exist within the associated firmware
  volume (it has a larger index than the last block of the
  firmware volume), the EraseBlocks() function must return the
  status code EFI_INVALID_PARAMETER without modifying the contents
  of the firmware volume. Implementations should be mindful that
  the firmware volume might be in the WriteDisabled state. If it
  is in this state, the EraseBlocks() function must return the
  status code EFI_ACCESS_DENIED without modifying the contents of
  the firmware volume. All calls to EraseBlocks() must be fully
  flushed to the hardware before the EraseBlocks() service
  returns.

  @param This   Indicates the EFI_FIRMWARE_VOLUME_BLOCK2_PROTOCOL
                instance.

  @param ...    The variable argument list is a list of tuples.
                Each tuple describes a range of LBAs to erase
                and consists of the following:
                - An EFI_LBA that indicates the starting LBA
                - A UINTN that indicates the number of blocks to
                  erase

                The list is terminated with an
                EFI_LBA_LIST_TERMINATOR. For example, the
                following indicates that two ranges of blocks
                (5-7 and 10-11) are to be erased: EraseBlocks
                (This, 5, 3, 10, 2, EFI_LBA_LIST_TERMINATOR);

  @retval EFI_SUCCESS The erase request was successfully
                      completed.
  
  @retval EFI_ACCESS_DENIED   The firmware volume is in the
                              WriteDisabled state.
  @retval EFI_DEVICE_ERROR  The block device is not functioning
                            correctly and could not be written.
                            The firmware device may have been
                            partially erased.
  @retval EFI_INVALID_PARAMETER One or more of the LBAs listed
                                in the variable argument list do
                                not exist in the firmware volume.
