Subject: [PATCH net 2/4] bnxt_en: Don't overload fw_vnic_id for RSS context's filters

From: Pavan Chebbi <pavan.chebbi@...adcom.com>

Currently the ntuple filters installed for an RSS context
use the ntuple filter's base member 'fw_vnic_id' to save the
RSS context id. This is making the fw_vnic_id overloaded when it
is being used with RSS context. This is very confusing.

Make explicit provision to save rss_ctx_id in the ntuple filter
so that we can avoid overloading fw_vnic_id.
Also remove unnecessary initialization of the id to 0.

This cleanup is necessary for the next patch that will remove
the fw_vnic_id field.
