[PATCH v2] net/iavf: fix iavf crashed on dev_stop when running in multi-process mode

[Ke Zhang]

In the multi process environment, the sub process
operates on the shared memory and changes the
function pointer of the main process, resulting in
the failure to find the address of the function when
main process releasing, resulting in crash.
