io_uring/net: refactor io_sr_msg types
In preparation for using struct io_sr_msg for zerocopy sends, clean up types. First, flags can be u16 as it's provided by the userspace in u16 ioprio, as well as addr_len. This saves us 4 bytes. Also use unsigned for size and done_io, both are as well limited to u32.
