ice: Rebuild TC queues on VSI queue reconfiguration

Browse Source 
[ Upstream commit f4b91c1d17 ]

TC queues needs to be correctly updated when the number of queues on
a VSI is reconfigured, so netdev's queue and TC settings will be
dynamically adjusted and could accurately represent the underlying
hardware state after changes to the VSI queue counts.

Fixes: 0754d65bd4 ("ice: Add infrastructure for mqprio support via ndo_setup_tc")
