[PATCH] fs:partitions:efi.c: bugfix a issue in find_valid_gpt

[wangyanqing <udknight@gmail.com>]

I meet a 3T disk, which partitioned by Windows 7,
and linux report unknow partition table. But it can been
detected the partition table when I add gpt to boot
parameter.

This issue caused by the find_valid_gpt function will fail
out when check the legacy mbr failed if there is no gpt boot
parameter.

if boot without gpt, we should fail back to check the guid
partition table when check the legacy mbr failed instead of
fail out.
