">> 5" rather than ">> 4"
vlan id is a 12 bit value.
VFTA is 128 x 32 bit array (128 double word array) which could store 2^12 vlan bits.
Each bit represents whether corresponding vlan tag is set in the VSI.
Use high 7 bits as the index for the double word array.

Add two macros I40E_VFTA_IDX and I40E_VFTA_BIT for vlan filter search and set.
Add vlan_id check in vlan filter search and set function.
