staging: rtl8723bs: use mac_pton() in rtw_macaddr_cfg()
Use the mac_pton() helper to convert the mac address string.
The functions key_char2num() and key_2char2num() are not used
anywhere else and can be removed.
This also has the benefit of validating the input since mac_pton()
returns false if the string is not valid.
