drm/radeon/ci_dpm: Remove set but unused variable 'dpm_event_src'

And the piece of code that has never been executed.

Fixes the following W=1 kernel build warning(s):

 drivers/gpu/drm/radeon/ci_dpm.c: In function ‘ci_set_dpm_event_sources’:
 drivers/gpu/drm/radeon/ci_dpm.c:1369:28: warning: variable ‘dpm_event_src’ set but not used [-Wunused-but-set-variable]
