Qi Zhang a85f5a914a net/ice/base: allocate and free RSS global lookup table 
Currently there is no API to allocate and free a RSS global LUT.
Incoming changes to support VFs having >16 queues will require using
RSS global LUT resources. The functions included will allow a PF to
configure a RSS global LUT for VFs that request >16 queues.
