drm/i915/gt: prevent forcewake releases during BAR resize

Tests on DG2 machines show that releasing forcewakes during BAR resize
results later in forcewake ack timeouts. Since forcewakes can be realeased
asynchronously the simplest way to prevent it is to get all forcewakes
for duration of BAR resizing.

v2: hold rpm as well during resizing (Rodrigo)
