dlm: make posix locks interruptible
Replace wait_event_killable with wait_event_interruptible so that a program waiting for a posix lock can be interrupted by a signal. With the killable version, a program was not interruptible by a signal if it had a signal handler set for it, overriding the default action of terminating the process.
