tty: Fix unbalanced BKL handling in error path
commit 77945febbe60a69e9dcab7f49d33a1aa1e436973 upstream.
Arnd noted:
After the "retry_open:" label, we first get the tty_mutex
and then the BKL. However a the end of tty_open, we jump
back to retry_open with the BKL still held. If we run into
this case, the tty_open function will be left with the BKL
still held.
