Commit 91fdbce7 ("ice: Add support in the driver for associating
queue with napi") invoked the netif_queue_set_napi() call. This
kernel function requires to be called with rtnl_lock taken,
otherwise ASSERT_RTNL() warning will be triggered. ice_vsi_rebuild()
initiating this call is under rtnl_lock when the rebuild is in
response to configuration changes from external interfaces (such as
tc, ethtool etc. which holds the lock). But, the VSI rebuild
generated from service tasks and resets (PFR/CORER/GLOBR) is not
under rtnl lock protection. Handle these cases as well to hold lock
before the kernel call (by setting the 'locked' boolean to false).

netif_queue_set_napi() is also used to clear previously set napi
in the q_vector unroll flow. Handle this for locked/lockless execution
paths.
