[PATCH 2/3] copy: Use source file size as length while performing sparse_copy

[Goldwyn Rodrigues]

From: Goldwyn Rodrigues <address@hidden>

We wish to copy until the end of the file. However, since we know the
size of the source, we can request the size to copy.

This is a prepatory patch for copy_file_range() because it would
return an error if you attempt to copy beyond the source file size.
