Markus Armbruster 939caddc2c qga-win: Fix guest-get-devices error API violations
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.

qmp_guest_get_devices() is wrong that way: it calls error_setg() in a
loop.

If no iteration fails, the function returns a value and sets no error.
Okay.

If exactly one iteration fails, the function returns a value and sets
an error.  Wrong.

If multiple iterations fail, the function trips error_setv()'s
assertion.

Fix it to return immediately on error.

Perhaps the failure to convert the driver version to UTF-8 should not
be an error.  We could simply not report the botched version string
instead.

Drop a superfluous continue while there.
