[Intel-gfx] [PATCH] drm/i915/gt: Fix use of static in macro mismatch

The INTEL_GT_RPS_SYSFS_ATTR was creating to different structures
but. When called with the "static" keyword this is affecting only
the first structure, while the second is created as non static.

Move the static keyword inside the macros to affect both the
structures.
