Return to start() function when check_ssh_target failed

Browse Source 
In old code, kdumpctl program exit directly when check_ssh_target failed
without printing "Starting kdump: FAILED". Then when manually invoke
"kdumpctl restart", only print "Stopping kdump: OK", but no "Starting
kdump: FAILED". That is unreasonable.

In this patch change check_ssh_target() to return when it failed. Then
check the returned value in start() function and print status if the
returned value is not 0.

Meanwhile change "space" to "tab" in function check_ssh_target(), make
those be consistent with the whole script file.
