Eric Biggers e5465795ca ext4: fix off-by-one error when writing back pages before dio read ...

The 'lend' argument of filemap_write_and_wait_range() is inclusive, so
we need to subtract 1 from pos + count.

Note that 'count' is guaranteed to be nonzero since
ext4_file_read_iter() returns early when given a 0 count.
