efi_loader: disk: Fix CONFIG_BLK breakage
When using CONFIG_BLK, there were 2 issues:
1) The name we generate the device with has to match the
name we set in efi_set_bootdev()
2) The device we pass into our block functions was wrong,
we should not rediscover it but just use the already known
pointer.
This patch fixes both issues.
