SUNRPC: change locking for xs_swap_enable/disable

Browse source

It is not in general safe to wait for XPRT_LOCKED to clear.
A wakeup is only sent when
 - connection completes
 - sock close completes
so during normal operations, this can wait indefinitely.

The event we need to protect against is ->inet being set to NULL, and
that happens under the recv_mutex lock.

So drop the handlign of XPRT_LOCKED and use recv_mutex instead.
