iomap: constrain the file range passed to iomap_file_unshare
[ Upstream commit a311a08a4237241fb5b9d219d3e33346de6e83e0 ]
File contents can only be shared (i.e. reflinked) below EOF, so it makes
no sense to try to unshare ranges beyond EOF. Constrain the file range
parameters here so that we don't have to do that in the callers.
