SUNRPC: Create a helper to tell whether a transport is bound
Hide the contents and format of xprt->addr by eliminating direct uses
of the xprt->addr.sin_port field. This change is required to support
alternate RPC host address formats (eg IPv6).
Test-plan:
Destructive testing (unplugging the network temporarily). Repeated runs of
Connectathon locking suite with UDP and TCP.
