[PATCH] staging: rtl8723bs: Remove unused ifname module parameter

[Svyatoslav Nikolenko]

Remove the ifname module parameter and the corresponding ifname field in
struct registry_priv. Hardcode the default "wlan%d" interface name format
string directly in rtw_drv_register_netdev().

Close, but really, why are we saying "wlan" at all?  Why not use the
default wifi network naming like it is supposed to be using?  The whole
callpath here that sets the device name can probably be removed as the
networking core should handle that for us, right?
