Fix data race in fs.Async.
Replaces the WaitGroup with a RWMutex. Calls to Async hold the mutex for reading, while AsyncBarrier takes the lock for writing. This ensures that all executing Async work finishes before AsyncBarrier returns. Also pushes the Async() call from Inode.Release into gofer/InodeOperations.Release(). This removes a recursive Async call which should not have been allowed in the first place. The gofer Release call is the slow one (since it may make RPCs to the gofer), so putting the Async call there makes sense.
