hw/arm/virt: Fix property "gic-version" error handling

Browse Source 
virt_set_gic_version() calls exit(1) when passed an invalid property
value.  Property setters are not supposed to do that.  Screwed up in
commit b92ad39.  Harmless, because the property belongs to a machine.
Set an error object instead.
