[PATCH] virsh: Simplify @flags handing in cmdSetmem() and cmdSetmaxmem()
What code tries to achieve is that if no flags were provided to
either 'setmem' or 'setmaxmem' commands then the old (no flags)
API is called to be able to communicate with older daemons.
Well, the code can be simplified a bit.
Note that with this change the old no flag version of APIs is
used more often. Previously if --current argument was given it
resulted in *Flags() version to be called even though it is not
necessary - VIR_DOMAIN_AFFECT_CURRENT is implied.
Therefore, this change in fact allows virsh to talk with broader
set of daemons.
