can: softing_cs: softingcs_probe(): fix memleak on registration failure
commit ced4913efb0acc844ed65cc01d091a85d83a2082 upstream.
In case device registration fails during probe, the driver state and
the embedded platform device structure needs to be freed using
platform_device_put() to properly free all resources (e.g. the device
name).
Fixes: 0a0b7a5f7a04 ("can: add driver for Softing card")
