[PATCH 1/5] staging: rtl8723bs: remove unused code

[Michael Straube]

Remove commented rtw_is_cckrates_included() and
rtw_is_cckratesonly_included() from os_dep/ioctl_linux.c.
Both are defined in core/rtw_ieee80211.c.

[PATCH 4/5] staging: rtl8723bs: change return type to bool

[Michael Straube]

Both rtw_is_cckrates_included() and rtw_is_cckratesonly_included()
return true or false. Change the return type from uint to bool.
