Wei Gao c8e0967400 ext2: Handle fiemap on empty files to prevent EINVAL ...

[ Upstream commit a099b09a33 ]

Previously, ext2_fiemap would unconditionally apply "len = min_t(u64, len,
i_size_read(inode));", When inode->i_size was 0 (for an empty file), this
would reduce the requested len to 0. Passing len = 0 to iomap_fiemap could
then result in an -EINVAL error, even for valid queries on empty files.
