xfs: fix superblock inprogress check
commit f3d7ebdeb2c297bd26272384e955033493ca291c upstream.
From inspection, the superblock sb_inprogress check is done in the
verifier and triggered only for the primary superblock via a
"bp->b_bn == XFS_SB_DADDR" check.
Unfortunately, the primary superblock is an uncached buffer, and
hence it is configured by xfs_buf_read_uncached() with:
bp->b_bn = XFS_BUF_DADDR_NULL; /* always null for uncached buffers */
And so this check never triggers. Fix it.
