ELF/BFD: Propagate the return status from backend section processing

Fix the issue of any failure from `->elf_backend_section_processing'
not being propagated by `_bfd_elf_write_object_contents'.  The MIPS
`_bfd_mips_elf_section_processing' handler can actually potentially
fail, however the caller currently ignores that.

	* elf.c (_bfd_elf_write_object_contents): Propagate a failure
	status from `->elf_backend_section_processing'.
