Fix 2.4 for pcmcia-ti-routing-9_v24.patch

Hi, Daniel and everybody!

pcmcia-ti-routing-9_v24.patch is totally broken.  socket->probe_status is
never set to anything but 0.  yenta_probe_handler() fails always.  The
code that sets socket->probe_status to 1 in yenta_probe_handler() was lost
during backporting.

Please apply the attached patch on top of pcmcia-ti-routing-9_v24.patch.
It has been tested.  The patch can be combined with
pcmcia-ti-routing-9_v24.patch using "combinediff" from patchutils.

I believe pcmcia-ti-routing-9_v24.patch should be removed from the
website.  It cannot work for anybody.  There are direct links to that file,
and people will waste their time is they try it.

Many thanks to Warren Melnick and Jonathan Sambrook for reporting this
