bnep:Fix variable assignment to function return value in the function bnep_rx_extenstion

This fixes variable assignment for the variable err that returns to the caller of bnep_rx_extension has finish all its intended work or has failed by returning a error code to be properly assigned to the return value of the call to the function bnep_rx_control due to this function being able to fail and callers of bnep_rx_extension needing to be able to properly be signaled when this occurs.
