Add a missing assert argument, fixes:
zephyrproject/zephyr/kernel/dynamic.c: In function 'dyn_cb':
zephyrproject/zephyr/include/zephyr/sys/__assert.h:44:52: warning:
format '%p' expects a matching 'void *' argument [-Wformat=]
That started to break the build since:
d7846de548 assert: check format arguments for correctness
