The current implementation fails on devices with less than 32k of
flash (such as several devices in the Zero Gecko family) because
the 'assert' assumes (incorrectly) that the number of flash banks
will always be >= 32.
This change ensures that at least one word of lock bits is always read
in order to support devices with less than 32k of flash.
