[PATCH net 1/8] ice: fix FDIR CTRL VSI resource leak in ice_reset_all_vfs()

[Tony Nguyen <anthony.l.nguyen@intel.com>]

From: Dawid Osuchowski <dawid.osuchowski@linux.intel.com>

Resetting all VFs causes resource leak on VFs with FDIR filters
enabled as CTRL VSIs are only invalidated and not freed. Fix by using
ice_vf_ctrl_vsi_release() instead of ice_vf_ctrl_invalidate_vsi() which
aligns behavior with the ice_reset_vf() function.

Reproduction:
  echo 1 > /sys/class/net/$pf/device/sriov_numvfs
  ethtool -N $vf flow-type ether proto 0x9000 action 0
  echo 1 > /sys/class/net/$pf/device/reset

Fixes: da62c5ff9dcd ("ice: Add support for per VF ctrl VSI enabling")
