[ upstream commit fced83c1229e0ad89f26d07fa7bd46b8767d9f5c ]
In the multiple process environment, the subprocess 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.
Fixes: 319c421f3890 ("net/avf: enable SSE Rx Tx")
