Kernel: getproc() should not enable interrupts if it is called from
within an interrupt handler because we cannot handle any interrupts that
arrive as a result. Enable interrupts only when no process is ready,
which is obviously never the case when we're preempting a process from
within a timer interrupt. The kernel will also panic if we're about to
enable interrupts in getproc() when we're already handling one.
