Users report timeout-new fails. Don't return an error for older kernels
not supporting IORING_FEAT_EXT_ARG, just skip it.

Use inet_aton() to set address, otherwise can lead to problems depending
on endianness.

Also, set user_data only after io_uring_prep_link_timeout(), otherwise
will be rewritten.
