f2fs: return symlink writeback errors

Browse source

F2FS writes long symlink data with page_symlink() and then flushes the
symlink mapping to reduce the chance of exposing a broken symlink.

That flush result is currently ignored. If the writeback fails, symlink()
still returns success even though the symlink is not durable and the same
operation can already surface -EIO through syncfs().

Return the writeback error to userspace and skip the dirsync flush once the
symlink data flush has failed.
