Drop slot's LWLock before returning from SaveSlotToPath() When SaveSlotToPath() is called with elevel=LOG, the early exits didn't release the slot's io_in_progress_lock.
This could result in a walsender being stuck on the lock forever. A possible way to get into this situation is if the offending code paths are triggered in a low disk space situation.
