power: sequencing: fix NULL-pointer dereference in pwrseq_device_register()

Browse source

If dev_set_name() fails in pwrseq_device_register(), we jump to the
err_put_pwrseq label before initializing pwrseq->targets.
pwrseq_release() will try to iterate over targets unconditionally and
subsequently dereference an invalid pointer. Move the call to
dev_set_name() after the list head is initialized.
