[AFS]: Eliminate cmpxchg() usage in vlocation code.
cmpxchg() is not available on every processor so can't be used in generic code. Replace with spinlock protection on the ->state changes, wakeups, and wait loops. Add what appears to be a missing wakeup on transition to AFS_VL_VALID state in afs_vlocation_updater(). Signed-off-by: David S. Miller <davem@davemloft.net>
