[libvirt] [PATCH 3/3] virsh: Error out if VSH_OT_STRING option has VSH_OFLAG_REQ flag

[Martin Kletzander]

Recent commit 12bd207e217f3c5dc2272a5ea943b81067bd8034 fixed few
VSH_OT_STRING options that should've been VSH_OT_DATA.  That lead me to
this commit that enforces people to check that newly added options have
proper type.  Thanks to virsh erroring out with error message, this will
immediately show up in 'make check' thanks to our virsh-synopsis test.
