ice: Add code for DCB initialization part 3/4
This patch adds a new function ice_pf_dcb_cfg (and related helpers)
which applies the DCB configuration obtained from the firmware. As
part of this, VSIs/netdevs are updated with traffic class information.
This patch requires a bit of a refactor of existing code.
1. For a MIB change event, the associated VSI is closed and brought up
again. The gap between closing and opening the VSI can cause a race
condition. Fix this by grabbing the rtnl_lock prior to closing the
VSI and then only free it after re-opening the VSI during a MIB
change event.
2. ice_sched_query_elem is used in ice_sched.c and with this patch, in
ice_dcb.c as well. However, ice_dcb.c is not built when CONFIG_DCB is
unset. This results in namespace warnings (ice_sched.o: Externally
defined symbols with no external references) when CONFIG_DCB is unset.
To avoid this move ice_sched_query_elem from ice_sched.c to
ice_common.c.
