staging: rtl8723bs: drop unnessary dep on CFG80211_WEXT

In commit 174ac41a7aaf ("staging: rtl8723bs: remove obsolete wext
support") a dep on CFG80211_WEXT was added to allow wext userspace
calls to be managed via the compatibility support. This is an
optional dependency which the driver has no dependency on and
stops users/distros etc from dropping CFG80211_WEXT if they want
to enable this driver. Drop this dependency as if users want this
legacy feature they will be explicitly enabling it themselves.
