According to the PI spec, Volume 3, EFI_FIRMWARE_VOLUME_BLOCK2_PROTOCOL.EraseBlocks():
> 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 (NB, in edk2, EFI_FIRMWARE_VOLUME_BLOCK_PROTOCOL is a typedef to EFI_FIRMWARE_VOLUME_BLOCK2_PROTOCOL.) In this driver, the NumOfLba local variable is defined with type UINTN, but the TYPE argument passed to VA_ARG() is UINT32. Fix the mismatch.
