From: Masayoshi Mizuma <m.mizuma@xxxxxxxxxxxxxx>
commit 25195eb ("xfsdump: handle bind mount target") introduced
a bug of xfsdump which doesn't store the files to the dump file
correctly when the root inode number is changed.
The commit 25195eb is reverted, and commit 0717c1c ("xfsdump: intercept
bind mount targets") which is in xfsdump v3.1.10 fixes the bug to reject
the filesystem if it's bind-mounted.
Test that xfsdump can reject the bind-mounted filesystem.
