Subject: [PATCH 5.15 16/42] ice: fix FDIR init missing when reset VF

From: Yahui Cao <yahui.cao@...el.com>

[ Upstream commit f23ab04dd6f703e282bb2d51fe3ae14f4b88a628 ]

When VF is being reset, ice_reset_vf() will be called and FDIR
resource should be released and initialized again.

Fixes: 1f7ea1cd6a37 ("ice: Enable FDIR Configure for AVF")
