Fix crash when disabling focused mon

m->link.next leads to errors if the monitor to disable doesn't have a
"next" (right) monitor and is currently focused. dirtmon() does more
checks.

In some previous commits m->link.next is told to be left monitor, which
is wrong

Also focusclient() explicitly checks for disabled monitors (this fixes
in case of more than one disabled monitor)
