Dracut will drop into shell in case anything wrong with rootfs mounting,
but for kdump we does not depends on rootfs for non-rootfs dump and
kdump will handle the default fail action based on user configuration
in /etc/kdump.conf.
Here call exception_handle_check and specify a handler continue_on_fail.
If user add a cmdline like rd.exceptionhandler=continue_on_fail, then
go on. If no cmdline rd.exceptionhandler=continue_on_fail added, just
drop into shell as before.

In below code "$$" should be "&&". I tested this patchset by changing
mount-loop limitation count to 1.
