[PATCH v4 4/6] generic/223: Don't clear all mkfs options for _scratch_mkfs_geom() roughly

[Xiao Yang <yangx.jy@cn.fujitsu.com>]

ext4 can accept the last one if the same mkfs options are passed but xfs cannot
accept the same mkfs options and reports "xxx option is respecified" error.  I
prefer to override the same mkfs option which is defined in MKFS_OPTION so that
we can have a chance to pass other mkfs options to _scratch_mkfs_geom().
