RDMA/restrack: don't use uaccess_kernel()
uaccess_kernel() isn't sufficient to determine if an rdma resource is
user-mode or not. For example, resources allocated in the add_one()
function of an ib_client get falsely labeled as user mode, when they
are kernel mode allocations. EG: mad qps.
The result is that these qps are skipped over during a nldev query
because of an erroneous namespace mismatch.
So now we determine if the resource is user-mode by looking at the object
struct's uobject or similar pointer to know if it was allocated for user
mode applications.
