[ upstream commit 0b048557db761d287777360a100e1d010760d209 ]
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.
