sunrpc: fixes and cleanups for svc creation and thread handling

Hi Bruce!

Patch #1 in this series is a bugfix, but probably isn't worth sending to stable. The rest are just cleanups in preparation for some other patches that I have queued up. Can you consider these for 3.19?

The main one that I'm hoping to send soon for v3.19 is the one to help reduce the pool->sp_lock contention on busy servers. I have some preliminary numbers that look pretty good, but one of our QA folks is working on getting some better ones from a more rigorous test. I'll send those along in a few days once I have those numbers.

Jeff Layton (10):
sunrpc: release svc_pool_map reference when serv allocation fails
sunrpc: add a generic rq_flags field to svc_rqst and move rq_secure to
it
sunrpc: move rq_local field to rq_flags
sunrpc: move rq_usedeferral flag to rq_flags
sunrpc: move rq_dropme flag into rq_flags
sunrpc: move rq_splice_ok flag into rq_flags
sunrpc: move rq_cachetype field to better optimize space
sunrpc: convert sp_task_pending flag to use atomic bitops
sunrpc: have svc_wake_up only deal with pool 0
sunrpc: require svc_create callers to pass in meaningful shutdown
routine
