[IA64-SGI] Double spin_unlock in bte.c

If all bte interfaces are in use, the current code will leave the
bte pointer set when exiting from the loop trying to locate an
interface to use.  This results in two processes using the same
interface and both trying to free the same one.  With a
premptible kernel, this results in the preempt count getting
off.
