[PATCH] NFS: Fix typo in nfs_get_client()
Commit ca4aa09635516258f158a7bc1594a794e4c34864 fixed waiting for the
structure to get initialised, but it is also possible to break out of
the loop while still in TASK_INTERRUPTIBLE.
Replace the whole thing by wait_event_interruptible, which is much more
readable, and doesn't suffer from these problems.
