Benjamin Tissoires 467fce636a HID: bpf: actually free hdev memory after attaching a HID-BPF program 
commit 89be8aa5b0 upstream.

Turns out that I got my reference counts wrong and each successful
bus_find_device() actually calls get_device(), and we need to manually
call put_device().

Ensure each bus_find_device() gets a matching put_device() when releasing
the bpf programs and fix all the error paths.
