Darrick J. Wong 5c989a0ee0 xfs: remove dest file's post-eof preallocations before reflinking 
If we try to reflink into a file with post-eof preallocations at an
offset well past the preallocations, we increase i_size as one would
expect.  However, those allocations do not have page cache backing them,
so they won't get cleaned out on their own.  This leads to asserts in
the collapse/insert range code and xfs_destroy_inode when they encounter
delalloc extents they weren't expecting to find.

Since there are plenty of other places where we dump those post-eof
blocks, do the same to the reflink destination file before we start
remapping extents.  This was found by adding clonerange support to
fsstress and running it in write-only mode.
