tests/kernel/fatal: Don't swap while locked
This test takes an interrupt lock and tries to call z_swap_unlocked()
while holding it. That's not legal (in the general case it means
you're breaking a caller's lock!), though in this particular case it
was safe because we'll never return to this.
Regardless, there is a natural z_swap_irqlock() that releases the lock
atomically. Use that.
