net: qrtr: ns: Change servers radix tree to xarray
There is a use after free scenario while iterating through the servers
radix tree despite the ns being a single threaded process. This can
happen when the radix tree APIs are not synchronized with the
rcu_read_lock() APIs.
Convert the radix tree for servers to xarray to take advantage of the
built in rcu lock usage provided by xarray.
