sys/linux: don't use len/flags/const/proc types in out fields
Remove all uses of len/flags/const/proc types in explicitly marked out fields.
Use of these types for out fields does not make sense:
a len[b, int32] (out)
b flags[foo, int32] (out)
Since kernel fills these fields, that's unnecessary details or bugs in descriptions.
In particular all of these are actually bugs:
ioctl$TUNSETQUEUE(fd fd_tun, cmd const[TUNSETQUEUE], arg ptr[in, ifreq_t[flags[tun_queue_flags, int16]]])
ioctl$TUNSETIFF(fd fd_tun, cmd const[TUNSETIFF], arg ptr[in, ifreq_t[flags[tun_setiff_flags, int16]]])
ioctl$SIOCSIFHWADDR(fd fd_tun, cmd const[SIOCSIFHWADDR], arg ptr[in, ifreq_t[mac_addr]])
ioctl$sock_inet_SIOCSIFADDR(fd sock, cmd const[SIOCSIFADDR], arg ptr[inout, ifreq_t[sockaddr_in]])
ioctl$sock_inet_SIOCSIFBRDADDR(fd sock, cmd const[SIOCSIFBRDADDR], arg ptr[inout, ifreq_t[sockaddr_in]])
ioctl$sock_inet_SIOCSIFNETMASK(fd sock, cmd const[SIOCSIFNETMASK], arg ptr[inout, ifreq_t[sockaddr_in]])
ioctl$sock_inet_SIOCSIFDSTADDR(fd sock, cmd const[SIOCSIFDSTADDR], arg ptr[inout, ifreq_t[sockaddr_in]])
ioctl$sock_inet_SIOCSIFPFLAGS(fd sock, cmd const[SIOCSIFPFLAGS], arg ptr[inout, ifreq_t[int32]])
ioctl$SIOCSIFMTU(fd sock_pppl2tp, cmd const[SIOCSIFMTU], arg ptr[in, ifreq_t[int32]])
ioctl$sock_SIOCETHTOOL(fd sock, cmd const[SIOCETHTOOL], arg ptr[inout, ifreq_t[ptr[inout, ethtool_cmd_u]]])
We pretend that we pass in some flags or addresses, but the ifreq field
was marked as (out), so we actually did not pass anything in.
