Chuck Lever ea888a14ac SUNRPC: Mitigate cond_resched() in xprt_transmit()
[ Upstream commit 6f9f17287e ]

The original purpose of this expensive call is to prevent a long
queue of requests from blocking other work.

The cond_resched() call is unnecessary after just a single send
operation.

For longer queues, instead of invoking the kernel scheduler, simply
release the transport send lock and return to the RPC scheduler.
