ixgbe: always perform vector Rx setup if vpmd enabled

Browse Source 
If the vector pmd option is turned on in the compile time config file,
then always call the vector rxq setup, since we can now use the vector
PMD for receiving jumbo frames that need chained mbufs, a.k.a scattered
packets. Up till now, this function was not being called when receiving
scattered packets, potentially leading to problems with mbufs not being
properly initialized.
