mke2fs: allow setting the stride and stripe width to zero 

Mke2fs previously would give an error if the user tried setting the
stride and stripe-width parameters to zero; but this is necessary to
override the stride and stripe-width settings which get automatically
set from the block device's geometry information in sysfs.  So allow
setting these parameters to zero.
