remote generator: handle remoteDomainCreateWithFlags()

remote generator: handle remoteDomainCreateWithFlags()

This commit removes the handcrafted code for
remoteDomainCreateWithFlags() and lets it auto generate.

A little bit of history repeating...
Commit 03d813bbcd7b4a183601055006 removed the auto generation of
remoteDomainCreateWithFlags() because it was thought that the design
flaw in the remote protocol for virDomainCreate is also within the
remote protocol for virDomainCreateWithFlags. As the commit message of
ddaf15d7a3863d54e242f8ff75 mentions this is not the case therefore we
can auto generate the client part.

Even worse there was a typo in remoteDomainCreateWithFlags()

'remote_domain_create_with_flags_args ret;' but in fact it has to be
'remote_domain_create_with_flags_ret ret;'.
