[PATCH v2 1/1] fs/binfmt_elf_fdpic: fix error return code in load_elf_fdpic_binary()

[Zhen Lei]

When the call to create_elf_fdpic_tables() fails, the returned error code
should be propagated. However, we currently do not explicitly assign this
error code to 'retval'. As a result, 0 was incorrectly returned.

Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
