can: flexcan: flexcan_chip_stop(): add error handling and propagate error value

This patch implements error handling and propagates the error value of
flexcan_chip_stop(). This function will be called from flexcan_suspend()
in an upcoming patch in some SoCs which support LPSR mode.

Add a new function flexcan_chip_stop_disable_on_error() that tries to
disable the chip even in case of errors.
