[PATCH] net/ice: fix RSS LUT access for global LUT VSI

[Vladimir Medvedkin]

When global RSS LUT is enabled, get/set RSS LUT still uses PF LUT
parameters in AQ commands, with lut_type set to PF and global_lut_id 0.
As a result, the operation may target the wrong LUT.

Use global LUT parameters when global LUT is allocated for the VSI,
and keep PF LUT parameters otherwise.
