Allow only one VSI to alloc the PF RSS LUT.
Shared part consists of just a new field, actual implementation will use
`rss_locks` to serialize the access. Take advantage of the fact that VSI #0 is
main VSI for PF, what is the default PF LUT holder, so zero-init of struct
ice_hw sets it as designed.

This is a one-line change, so can probably be merged into some other patch,
rather than needing a whole commit on its own.

preferably to the patch that is the first to use that new field,
I see none (but I'm not subscribed to the dpdk ML, so perhaps there is
some other in the series)
