RDMA/rtrs-clt: Fix possible double free in error case

Callback function rtrs_clt_dev_release() for put_device() calls kfree(clt)
to free memory. We shouldn't call kfree(clt) again, and we can't use the
clt after kfree too.

Replace device_register() with device_initialize() and device_add() so that
dev_set_name can() be used appropriately.

Move mutex_destroy() to the release function so it can be called in
the alloc_clt err path.
