    Load curlwp into a0 to call fpu_save(curlwp), not fpu_save(garbage).

    The lwp argument to fpu_save was added by chuq in revision 1.14 of
    mips_fpu.c, but this call was not updated to pass it.  This is the
    correct lwp to pass because we are in the middle of executing a
    kernel-emulated fp instruction, so curlwp must own the fpu state, and
    we are trying to write the fp registers to memory so we can adjust
    them there when ctc1 would fail.

    Fixes PR port-cobalt/53090, PR port-sgimips/53791.
