[libvirt] [PATCH v2 2/3] qemu: Check return status for virDomainGraphicsListenSetAddress
Recent refactors in the vbox code to check the return status for the
function tipped Coverity's scales of justice for any functions that
do not check status - such as this one.
While I'm at it, since the call is essentially the same other than
whether starting from val or val+1 when val[0] = '[', just adjust
the val pointer by one and have one call instead of two.
