[MGW NAT] fix supervisor parameter passing, double-list for doubly-apply
There are two successive iterations of apply() being called, one by
the supervisor:start_one_child() logic, and the second time inside
the mgw_nat_usr:init() function calling sctp_handler:init(). To
make sure our list survives this as list instead of sequence of
arguments, we need to double-[] quote it.
