drm/xe: Fix a bug in pc_adjust_freq_bounds()

Browse source

In cases where min frequency was actually greater than BMG_MIN_FREQ,
we were not using the updated min frequency as there was a missing
call to pc_action_query_task_state() between the two settings of
min frequency. Since we know what min_freq was last set, use that
cached value while comparing to BMG_MIN_FREQ to fix this issue.

v2: pc->freq_ready is not set until after pc_adjust_freq_bounds(). Stay
with pc_action_query_task_state() instead.

v3: Update commit message (Stuart)
