drm/amd/display: Fix OTG disable workaround logic
[Why]
DENTIST was hanging when performing DISPCLK update with OTG enabled, as
OTG disable workaround was not executing.
[How]
Workaround was checking against current_state before running, but when
called from optimize_bandwidth (safe_to_lower), we should be checking
against context instead.
