md: raid0: remove setting of segment boundary.

Browse Source 
This setting doesn't seem to make sense (half the chunk size??) and
shouldn't be needed.
The segment boundary exported by raid0 should simply be the minimum
of the segment boundary of all component devices.  And we already
get that right.
