Asbjørn Sloth Tønnesen 600b665b90 io_uring/cmd_net: fix too strict requirement on ioctl 
Attempting SOCKET_URING_OP_SETSOCKOPT on an AF_NETLINK socket resulted
in an -EOPNOTSUPP, as AF_NETLINK doesn't have an ioctl in its struct
proto, but only in struct proto_ops.

Prior to the blamed commit, io_uring_cmd_sock() only had two cmd_op
operations, both requiring ioctl, thus the check was warranted.

Since then, 4 new cmd_op operations have been added, none of which
depend on ioctl. This patch moves the ioctl check, so it only applies
to the original operations.

AFAICT, the ioctl requirement was unintentional, and it wasn't
visible in the blamed patch within 3 lines of context.
