vl: Clean up error reporting in machine_set_property()

Calling error_report() in a function that takes an Error ** argument
is suspicious.  machine_set_property() does that, and then fails without
setting an error.  Its caller main(), via qemu_opts_foreach(), is fine
with it, but clean it up anyway.
