Revert "serial: omap: unlock the port lock"
This reverts commit 0324a821029e1f54e7a7f8fed48693cfce42dc0e.
That commit tried to fix a deadlock problem when using
hci_ldisc, but it turns out the bug was in hci_ldsic
all along where it was calling ->write() from within
->write_wakeup() callback.
The problem is that ->write_wakeup() was called with
port lock held and ->write() tried to grab the same
port lock.
