NeilBrown b49ea673e1 SUNRPC: lock against ->sock changing during sysfs read 
->sock can be set to NULL asynchronously unless ->recv_mutex is held.
So it is important to hold that mutex.  Otherwise a sysfs read can
trigger an oops.
Commit 17f09d3f61 ("SUNRPC: Check if the xprt is connected before
handling sysfs reads") appears to attempt to fix this problem, but it
only narrows the race window.

Fixes: 17f09d3f61 ("SUNRPC: Check if the xprt is connected before handling sysfs reads")
Fixes: a8482488a7 ("SUNRPC query transport's source port")
