net/utils: net_lock() and net_restorelock() not return a value. That values is the standard zero on success; negated errno value on failure. This return value is only needed for -ECANCELED. That cancellation indication needs to ripple all the way back to the highest levels where the cancellation can be acted on. This commit only adds the return value; it does not add checking for the return values of net_lock() and net_restorelock() at higher levels. That is required too.
