staging: rtl8187se: Remove unused functions 'rsn_authen_cipher_suite' and 'ext_ieee80211_send_beacon_wq'

Remove unused functions rsn_authen_cipher_suite() and
ext_ieee80211_send_beacon_wq() from ieee80211_softmac.c.

Fix sparse warnings:
drivers/staging/rtl8187se/ieee80211/ieee80211_softmac.c:27:11: warning: ‘rsn_authen_cipher_suite’ defined but not used [-Wunused-variable]
drivers/staging/rtl8187se/ieee80211/ieee80211_softmac.c:327:13: warning: ‘ext_ieee80211_send_beacon_wq’ defined but not used [-Wunused-function]
