s390/vfio-ap: fix an error handling path in vfio_ap_mdev_probe_queue()
The commit in Fixes: has switch the order of a sysfs_create_group() and a
kzalloc().
It correctly removed the now useless kfree() but forgot to add a
sysfs_remove_group() in case of (unlikely) memory allocation failure.
Add it now.
Fixes: 260f3ea14138 ("s390/vfio-ap: move probe and remove callbacks to vfio_ap_ops.c")
