[PATCH] mkfs: fix -l su minval

[Jan Tulak <jtulak@xxxxxxxxxx>]

-l su should be in range BBTOB(1) <= L_SU <= XLOG_MAX_RECORD_BSIZE, because the
upper limit is imposed by kernel on iclogbuf: stripe unit can't be bigger than
the log buffer, but the log buffer can span multiple stripe units. L_SUNIT is
changed in the same way.
