[PATCH] uefi: uefidump: fix the boot load option Boot#### larger than Boot1000 doesn't be parsered (LP:#1225850)

[Ivan Hu]

Some firmware/BIOS create the Boot path not in order, some of Boot load options
are created larger than "Boot1000", such as Boot1001, Boot2001 etc. The uefidump
checks the boot path with the "Boot0" causes these Boot load options cannot be
parsered.
