Re: [PATCH v2] xen/efi: Use blexit() instead of BUG_ON() in read_file()

Follow-up to 880e40b187aa, which added a BUG_ON() guard in read_file().
But as Jan pointed out, before ExitBootServices BUG_ON()
is not functional. It results in a hang with no message.
On the other hand blexit() prints a message and returns back
to the bootloader.
Fixes: 880e40b187aa ("xen/efi: Fix boot from a device without a file system")
