ice: Check VF VSI Pointer Value in ice_vc_add_fdir_fltr()

Browse Source 
[ Upstream commit 425c5f266b2edeee0ce16fedd8466410cdcfcfe3 ]

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: 6ebbe97a4881 ("ice: Add a per-VF limit on number of FDIR filters")
