bnxt_en: use link_lock instead of hwrm_cmd_lock to protect link_info
We currently use the hwrm_cmd_lock to serialize the update of the
firmware's link status response data and the copying of link status data
to the VF. This won't work when we update the firmware message APIs, so
we use the link_lock mutex instead. All link_info data should be
updated under the link_lock mutex. Also add link_lock to functions that
touch link_info in __bnxt_open_nic() and bnxt_probe_phy(). The locking
is probably not strictly necessary during probe, but it's more consistent.
