[PATCH] xfsprogs: tidy up xfs_fsr.c

[Eric Sandeen <sandeen@xxxxxxxxxxx>]

Make the mountpoint stat structure "ms" local to
find_mountpoint_check(), no caller uses it.  And remove 3rd
"sb2" statbuf in that same function, we can just re-use ms.

rename "struct mntent *mp" to "struct mntent *mnt" -
"mp" has its own common meaning in xfsprogs.

And a couple more minor whitespace removals.
