 /**
   Writes specified number of bytes from the input buffer to the block

   The EfiFvbWriteBlock() function writes the specified number of bytes
   from the provided buffer to the specified block and offset in the
   requested firmware volume.

   If the firmware volume is sticky write, the caller must ensure that
   all the bits of the specified range to write are in the EFI_FVB_ERASE_POLARITY
   state before calling the EfiFvbWriteBlock() function, or else the
   result will be unpredictable.  This unpredictability arises because,
   for a sticky-write firmware volume, a write may negate a bit in the
   EFI_FVB_ERASE_POLARITY state but it cannot flip it back again. In
   general, before calling the EfiFvbWriteBlock() function, the caller
   should call the EfiFvbEraseBlock() function first to erase the specified
   block to write. A block erase cycle will transition bits from the
   (NOT)EFI_FVB_ERASE_POLARITY state back to the EFI_FVB_ERASE_POLARITY state.
   Implementations should be mindful that the firmware volume might be
   in the WriteDisabled state.  If it is in this state, the EfiFvbWriteBlock()
   function must return the status code EFI_ACCESS_DENIED without modifying
