asan: mips_gprel_reloc segfault
Not just the undefined section has a NULL owner, the absolute section
has too. Which means we can't find output_bfd for __gp. Also, may as
well test directly for output_bfd == NULL.
* coff-mips.c (mips_gprel_reloc): Don't segfault on any of
bfd_is_const_section sections.
