During destroying the m2p mapping, the loop variable was always incremented
by one, as the current version used a compare operator on the left hand side,
which always evaluated to true, i.e.
i += 1UL < (L2_PAGETABLE_SHIFT - 2)
The fix increments the value of the variable by the actual page size by
using the shift operator instead.
