Jimmy Assarsson 1874f9143f can: kvaser_usb: Compare requested bittiming parameters with actual parameters in do_set_{,data}_bittiming

[ Upstream commit 39d3df6b0ea80f9b515c632ca07b39b1c156edee ]

The device will respond with a CMD_ERROR_EVENT command, with error_code
KVASER_USB_{LEAF,HYDRA}_ERROR_EVENT_PARAM, if the CMD_SET_BUSPARAMS_REQ
contains invalid bittiming parameters.
However, this command does not contain any channel reference.

To check if the CMD_SET_BUSPARAMS_REQ was successful, redback and compare
the requested bittiming parameters with the device reported parameters.

Fixes: 080f40a6fa28 ("can: kvaser_usb: Add support for Kvaser CAN/USB devices")
Fixes: aec5fb2268b7 ("can: kvaser_usb: Add support for Kvaser USB hydra family")
