iwlwifi: mvm: correct skip-over-DTIM implementation

Browse source

The formula used in D0i3 should also be used in D3, instead of
the hardcoded value.

Additionally, the formula is actually wrong - if the calculation
yields 0 then 1 should be used instead of disabling entirely.
Also need to add 1 since the firmware needs 3 to skip 2, etc.

To make all this clearer, centralize the calculation into a
single function.
