drm/msm: remove exra drm_kms_helper_poll_init() call

It seems during rebases I have left a call to drm_kms_helper_poll_init()
which is not guarded by the (priv->kms_init) check. This leads to the
crash for the boards which don't have KMS output. Drop this call, as
there is a correctly guarded one next to the one being removed.
