ice: Reset FDIR counter in FDIR init stage

Browse Source 
[ Upstream commit 83c911dc5e0e8e6eaa6431c06972a8f159bfe2fc ]

Reset the FDIR counters when FDIR inits. Without this patch,
when VF initializes or resets, all the FDIR counters are not
cleaned, which may cause unexpected behaviors for future FDIR
rule create (e.g., rule conflict).

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