[PATCH wireless-next v2 4/5] wifi: wilc1000: reject SET_BSS if any changed AP BSS param is not supported

[Gokul Sivakumar <gokulkumar.sivakumar@xxxxxxxxxxxx>]

Since the driver currently does not support setting any of the AP BSS
parameters, reject the entire SET_BSS operation instead of misleading the
userspace that the operation is fully successful.
