Subject: [PATCH] use fw_path prefix when fallback searching for grub config
When PXE booting via UEFI firmware, grub was searching for grub.cfg
in the fw_path directory where the grub application was found. If
that didn't exist, a fallback search would look for config file names
based on MAC and IP address. However, the search would look in the
prefix directory which may not be the same fw_path. This patch
changes that behavior to use the fw_path directory for the fallback
search. Only if fw_path is NULL will the prefix directory be searched.
