[ Upstream commit bada85a3f584763deadd201147778c3e791d279c ]
This function is supposed to return a uid on success, and an errno in failure. But it currently returns the return value of the specific cmd version handler, which in turn returns 0 on success and errno otherwise. This means that on success, iwl_mvm_build_scan_cmd will return 0 regardless if the actual uid. Fix this by returning the uid if the handler succeeded.
