admin: Remove flags checking from virAdmConnectOpen public API

Unlike the previous commit, we do actually support one client-side only flag
VIR_CONNECT_NO_ALIASES, so besides removing the check for flags this flag
has to be masked out before sending a message to the daemon, otherwise it
would trigger an error when checking flags on the daemon side.
