wifi: iwlwifi: mvm: return uid from iwl_mvm_build_scan_cmd

[ 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.
