sunrpc: Fix return value of get_srcport()
[ Upstream commit 5d46dd04cb68771f77ba66dbf6fd323a4a2ce00d ]
Since bc1c56e9bbe9 transport->srcport may by unset, causing
get_srcport() to return 0 when called. Fix this by querying the port
from the underlying socket instead of the transport.
Fixes: bc1c56e9bbe9 (SUNRPC: prevent port reuse on transports which don't request it)
