gssd: Fix file descriptor leak of old pipe dirs

gssd doesn't properly clean up internal state for old pipes and never
closes the (since deleted) clnt_info directory. This leads to eventual
fd exhaustion.

To reproduce, run a lot of mount / umounts in a loop and watch the
output of 'ls /proc/$PID/fdinfo | wc -l' (where PID is the pid of gssd)
steadily grow until gssd eventually crashes with "Too many open files".

This regression was introduced by 841e83c1, which was trying to fix a
similar bug in the skip matching logic of update_old_clients. The
problem with that patch is that pdir will never match dirname,
because dirname is "<pname>/clntXXX".
