    CRIS: fix PR ld/26589, a missing NULL check in fix for PR ld/22269

    Not sure why there wasn't a NULL check in the ld/22269 patch
    (e01c16a8) at the time, as there was one for the corresponding patch
    to elf32-m68k.c (5056ba1d).

    Incidentally, I had missed that in 2017, as a prerequisite for the
    ld/22269 series, the check_relocs function finally were made "safe"!
    (I.e. the number of references and symbol types are final, garbage
    collection done, so port-specific accounting can be made sanely.)

    Committed.

    bfd:
            PR ld/26589
            * elf32-cris.c (cris_elf_check_relocs): Add missing NULL check
            on argument before calling UNDEFWEAK_NO_DYNAMIC_RELOC.
