soc: ti: k3-ringacc: Add try_module_get() to k3_dmaring_request_dual_…
…ring() [ Upstream commit 5f1732a ] When the k3 ring accelerator driver has been modified to add module build support, try_module_get() and module_put() have been added to update the module refcnt. One code path has not been updated and it has introduced an issue where the refcnt is decremented by module_put() in k3_ringacc_ring_free() without being incremented previously. Adding try_module_get() to k3_dmaring_request_dual_ring() ensures the refcnt is kept up to date.
