wimax: fix oops if netlink fails to add attribute
When sending a message to user space using wimax_msg(), if nla_put() fails, correctly interpret the return code from wimax_msg_alloc() as an err ptr and return the error code instead of crashing (as it is assuming than non-NULL means the pointer is ok).
