drm/atomic-helper: Change parameter name of drm_atomic_helper_wait_for_flip_done()

drm_atomic_helper_wait_for_flip_done() will wait for pages flips on all
CRTCs affected by a given commit. It takes the drm_atomic_state being
committed as a parameter.

However, that parameter name is called (and documented) as old_state,
which is pretty confusing. Let's rename that variable as state.
