accel: Unbreak accelerator fallback
When the user specifies a list of accelerators, we pick the first one
that initializes successfully. Recent commit 1a3ec8c1564 broke that.
Reproducer:
$ qemu-system-x86_64 --machine accel=xen:tcg
xencall: error: Could not obtain handle on privileged command interface: No such file or directory
xen be core: xen be core: can't open xen interface
can't open xen interface
qemu-system-x86_64: failed to initialize Xen: Operation not permitted
qemu-system-x86_64: /home/armbru/work/qemu/qom/object.c:436: object_set_accelerator_compat_props: Assertion `!object_compat_props[0]' failed.
Root cause: we register accelerator compat properties even when the
accelerator fails. The failed assertion is
object_set_accelerator_compat_props() telling us off. Fix by calling
it only for the accelerator that succeeded.
