misc: enclosure: fix UAF on device_register() failure
After device_register() fails, the embedded struct device has already been
initialized and must be released with put_device() so that
enclosure_release() can drop the parent reference and free edev.
The error path currently does put_device(parent) + kfree(edev), which
skips the device lifetime rules and can free the object while the device
core still owns a reference (use-after-free).
