[PATCH v2 030/148] net/ice/base: limit PF RSS LUT to one VSI at time

[Anatoly Burakov]

From: Ian Stokes <ian.stokes at intel.com>

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.
