David Howells 19b073064f splice: Fix filemap_splice_read() to use the correct inode 
[ Upstream commit c37222082f ]

Fix filemap_splice_read() to use file->f_mapping->host, not file->f_inode,
as the source of the file size because in the case of a block device,
file->f_inode points to the block-special file (which is typically 0
length) and not the backing store.

Fixes: 07073eb01c ("splice: Add a func to do a splice from a buffered file without ITER_PIPE")
