dtlk: fix error checks in module_init()
This patch fixes two things in module_init.
- fix register_chrdev() error check
Currently dtlk doesn't check register_chrdev() failure correctly.
register_chrdev() returns a errno on failure.
- check probe failure
dtlk ignores probe failure and allows the module loading without
such device. I got "Trying to free nonexistent resource" message
by release_region() when unloading module without device.
