[Xenomai-core] [PATCH] Unfreeze timers when debugged target exits

[Jan Kiszka <jan.kiszka@domain.hid>]

I expressed my skepticism about this global timer freeze before :->, and
now it hit me unpleasantly (Customer: "Is it normal that Xenomai stops
working after the gdb session?" Jan [scratching head]: "Hmm, no...").

After more scratching I think I found the reason: The target decided to
die after some fault, but Xenomai missed to unfreeze the timers. Patch
below fixes that.

Without hearing complains, this also goes into trunk/2.4.x later today.
