Subject: [PATCH] Add missing rwlock_unlocks in xprt_register
It looks like in b2c9430f46c4ac848957fb8adaac176a3f6ac03f when svc_run
switched to poll, an early return was added, but the rwlock was not
unlocked.
I observed that rpcbind built against libtirpc-1.0.1 would handle only
one request before hanging, and tracked it down to a missing
rwlock_unlock here.
Fixes: b2c9430f46c4 ('Use poll() instead of select() in svc_run()')
