staging: rtl8723bs: remove return from void function

Remove exit label and return statement from a void function.
After the exit label no cleanup is done, so it is safe to remove it
and return early in the only place where the label is used.
This simplifies the code and clears a checkpatch warning.

WARNING: void function return statements are not generally useful
