can: bittiming: apply NL_SET_ERR_MSG() to can_calc_bittiming()

Browse source

When CONFIG_CAN_CALC_BITTIMING is disabled, the can_calc_bittiming()
functions can not be used and the user needs to provide all the
bittiming parameters.

Currently, can_calc_bittiming() prints an error message to the kernel
log. Instead use NL_SET_ERR_MSG() to make it return the error message
through the netlink interface so that the user can directly see it.
