[PATCH v2 11/11] staging: rtl8723bs: rtw_ieee80211: Reduce global symbols

[Priit Laes <plaes@plaes.org>]

Mark internally used symbols/functions as static and drop some unused
ones.
WPA_CIPHER_SUITE_WRAP/RSN_CIPHER_SUITE_WRAP are left as commented, as
these might be actually useful for understanding the code.

Changes since v1:
* Comment out unused variables WPA_CIPHER_SUITE_WRAP/RSN_CIPHER_SUITE_WRAP

Signed-off-by: Priit Laes <plaes@plaes.org>
