f2fs: ensure only power of 2 zone sizes are allowed

When using f2fs on zone storage drives we must be careful
to ensure that folks only work with power of 2 zone sizes.
Even though the block layer today enforces this these devices
do exist and some users are already hacking Linux to remove
these limitations. Prevent incorrect use of these devices as
a stop-gap measure.
