Flags checking should be done solely on the daemon side and therefore such
checks need to be removed from public APIs.

New subject: [libvirt] [PATCH 2/2] 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.

This won't mask out the flag, this will invert it.

Sigh...attempt n.2, see my fix in the attached patch.

I fixed the bitwise operation, adjusted the comment as you pointed out
and pushed, thanks.
