locks: don't allocate a lock context for an F_UNLCK request
In the event that we get an F_UNLCK request on an inode that has no lock
context, there is no reason to allocate one. Change
locks_get_lock_context to take a "type" pointer and avoid allocating a
new context if it's F_UNLCK.
Then, fix the callers to return appropriately if that function returns
NULL.
