[ Upstream commit 3fac2397f562eb669ddc2f45867a253f3fc26184 ]
When loading the driver for rtl8192e, the W_DISABLE# switch is working as intended. But when the WLAN is turned off in software and then turned on again the W_DISABLE# does not work anymore. Reason for this is that in the function _rtl92e_dm_check_rf_ctrl_gpio() the bfirst_after_down is checked and returned when true. bfirst_after_down is set true when switching the WLAN off in software. But it is not set to false again when WLAN is turned on again.
Add bfirst_after_down = false in _rtl92e_sta_up to reset bit and fix above described bug.
