when RTE_ENABLE_ASSERT is enable, DPAA driver is doing wrong NULL check on frame queue which allows the code to have access to NULL address. GCC v13 is giving array bounds error if code is accessing any memory region less than 4KB. This patch fixes this issue by adding proper NULL checks on frame queue.
