[U-Boot] [PATCH 12/15] x86: Fix off-by-one error in do_elf_reloc_fixups()

[Simon Glass]

From: Duncan Laurie <dlaurie at chromium.org>

The use of post-increment with a do-while loop results in
the loop going one step too far when handling relocation fixups.

In about 1/100 cases this would cause it to hang.
