[BUG] incorrect value of last block in block device protocol for partitions

The value for Media.LastBlock of the block IO protocol for partitions is incorrect for all partitions that do not end on the last block of the device.

lib/efi_loader/efi_disk.c(448) efi_disk_add_dev(): diskobj->media.last_block = desc->lba - offset;

desc->lba is the end of the disk not of the partition.
