[PATCH] xfstests 217: remove file in between mkfs's

[Eric Sandeen <sandeen@xxxxxxxxxxx>]

217 requires a 2G scratch:

_require_fs_space $SCRATCH_MNT 2202000

but as we mkfs different sizes, we actually are filling in the
sparse loopback more and more, and 3.8G isn't enough to contain it.

If we remove & recreate the file between mkfs's it doesn't take
so much space ... I don't think it adds significantly to test time.
