can: kvaser_usb: kvaser_usb_hydra_get_busparams(): fix memory leak in kvaser_usb_hydra_get_busparams()

Browse Source 
The memory allocated for cmd is not freed after the call to
kvaser_usb_send_cmd() in both the normal and error paths.
Fix that by adding a kfree() immediately after the call.

Fixes: 39d3df6b0e ("can: kvaser_usb: Compare requested bittiming parameters with actual parameters in do_set_{,data}_bittiming")
