If an interrupt occurs without a user defined callback, don't invoke the
function.
Otherwise, unexpected behavior will be seen due to running code from 0x0 (NULL).
Prior to this, it was the responsibility of the user to ensure all callbacks for
interrupts were set.

No need for this since the handler will never be called if the interrupts are
masked in the first place.
Also, by default, nested interrupts are disabled and it is up to the user to
explicitly request nested interrupts - allow this.
The interrupt mask should already apply in hardware.
