[ipxe-devel] [PATCH 2/3 v2] Call efi_boot_local() from efi_block_boot()

[Aaron Young]

Implement call to efi_boot_local() from efi_block_boot()
when there is no san_device defined for the given drive #.

This is will allow the sanboot command to attempt to boot
a local UEFI disk in the event that a drive was specified
for which there is no corrensponding san_device "hooked".
