protect the\nmulticast route list, so that it will not change while the driver\nperiodically traverses it in order to update the kernel about multicast\nroute stats that were queried from the device.\n\nOne instance of list entry deletion (during route replace) was missed\nand it can result in a use-after-free [1].\n\nFix by acquiring the mutex before deleting the entry from the list
