elf_fdpic: fix unused variable warning
The elf_fdpic code shows a harmless warning when built with MMU disabled,
I ran into this now that fdpic is available on ARM randconfig builds
since commit 50b2b2e691cd ("ARM: add ELF_FDPIC support").
fs/binfmt_elf_fdpic.c: In function 'elf_fdpic_dump_segments':
fs/binfmt_elf_fdpic.c:1501:17: error: unused variable 'addr' [-Werror=unused-variable]
This adds another #ifdef around the variable declaration to shut up
the warning.
Fixes: e6c1baa9b562 ("convert the rest of binfmt_elf_fdpic to dump_emit()")
