[PATCH] xfs_repair: Ensure just xfs_repair without -n can return a status code of 2

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

Since commit b04647edea32, xfs_repair -L could't succeed to clear a dirty log
and returned a status of 2.  Besides, xfs_repair -n returned a status of 2
instead of 1 if a dirty log was detected.  I think just xfs_repair without -n
should return a status code of 2 when getting a dirty log, so fix it.  We can
expose this issue by xfstests case xfs/098.

Fixes:'commit b04647edea32 ("xfs_repair: exit with status 2 if log dirtiness is unknown")'
