I am not entirely sure that I'm doing everything right, but in slapmodify the
fake operation has to set op->o_hdr for several functions to use, but has no
intention of setting o_tmpmfuncs. This makes slapd segfault when it is used with
back-mdb as it only checks whether o_hdr is set.

The last patch in the series at the above URL fixes this, but maybe some other
change is more appropriate.
