frv: elf32_frvfdpic_late_size_sections

This function runs passes over frvfdpic_relocs_info if dynobj is set,
which is OK since the two variables are both non-NULL or both NULL in
the current linker.  That may change in the future, so test
frvfdpic_relocs_info directly rather than dynobj.

	* elf32-frv.c (elf32_frvfdpic_late_size_sections): Omit dynobj
	test.  Instead test frvfdpic_relocs_info.
