f2fs: return writeback error from collapse range
f2fs_collapse_range() writes back pages moved by f2fs_do_collapse(),
but ignores the return value. If writeback fails, the ioctl can still
truncate page cache, shrink blocks, and report success.
Return the error before truncating page cache or updating the file size.
