ice: Check VF VSI Pointer Value in ice_vc_add_fdir_fltr()

Browse Source 
As mentioned in the commit baeb705fd6 ("ice: always check VF VSI
pointer values"), we need to perform a null pointer check on the return
value of ice_get_vf_vsi() before using it.

Fixes: 6ebbe97a48 ("ice: Add a per-VF limit on number of FDIR filters")
