slcand: move setting of loop variable back into code context

With commit 33a9249571 ("slcand: daemonise only once setup is complete")
the daemonize syscall is moved behind serial tty setup.

This patch moves the missing assignment of the loop variable slcand_running
to get it into the code context of the while() loop.
