staging: rtl8723bs: remove stale TODO item regarding %pM

The TODO list asks to "find codes that can use %pM and %Nph formatting".

A grep of the driver directory shows that no manual MAC address formatting
(using "%02x:%02x:..) remains in the code, thus all instances appear to have
been converted to use "%pM".

Remove the stale entry from the TODO list.
