From: Alan Brady <alan.br...@intel.com>

When using the debugfs to issue the "dump port" command
with NPAR enabled, the firmware reports back with invalid argument.

The issue occurs because the pf->mac_seid was used to perform the query.
This is fine when NPAR is disabled because the switch ID == pf->mac_seid,
however this is not the case when NPAR is enabled.  This fix instead
goes through the VSI to determine the correct ID to use in either case.
