Subject: [PATCH 3/3] staging: r8188eu: remove change_rfpwrstate

Remove the change_rfpwrstate component in struct pwrctrl_priv.

change_rfpwrstate is set to rf_off directly before each ips_enter call and
then checked in ips_enter. This makes no sense.

change_rfpwrstate might have been used to avoid conflicts between
suspend and resume operations. If a driver has to do this at all,
pwrpriv->ps_processing will do this job.
