qed: avoid possible stack overflow in qed_ll2_acquire_connection
struct qed_ll2_info is rather large, so putting it on the stack can cause an overflow, as this warning tries to tell us: drivers/net/ethernet/qlogic/qed/qed_ll2.c: In function 'qed_ll2_start': drivers/net/ethernet/qlogic/qed/qed_ll2.c:2159:1: error: the frame size of 1056 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] qed_ll2_start_ooo() already uses a dynamic allocation for the structure to work around that problem, and we could do the same in qed_ll2_start() as well as qed_roce_ll2_start(), but since the structure is only used to pass a couple of initialization values here, it seems nicer to replace it with a different structure. Lacking any idea for better naming, I'm adding 'struct qed_ll2_conn', which now contains all the initialization data, and this now simply gets copied into struct qed_ll2_info rather than assigning all members one by one.
