4.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jes Sorensen <Jes.Sorensen@redhat.com>
commit ab05e5ec81c76f3a852919c22984c885edd2414a upstream.
The generic disable_rf() function clears bits 22 and 23 in REG_RX_WAIT_CCA, however we did not re-enable them again in rtl8723b_enable_rf()
This resolves the problem for me with 8723bu devices not working again after reloading the driver.
