net: pcs: xpcs: correct pause resolution
xpcs was indicating symmetric pause should be enabled regardless of
the advertisements by either party. Fix this to use
linkmode_resolve_pause() now that we're no longer obliterating the
link partner's advertisement by logically anding it with our own.
This is transitional, the function will be entirely replaced with
phylink_resolve_c73() in the following patch.
