Alan Cox 6698e34720 tty: Fix BKL taken under a spinlock bug introduced in the BKL split ...

The fasync path takes the BKL (it probably doesn't need to in fact)
while holding the file_list spinlock.  You can't do that with the kernel
lock: it causes lock inversions and deadlocks.

Leave the BKL over that bit for the moment.
