Fix compilation error:

|
|
|
|||
|
|
super-intel.c: In function ‘end_migration’:
|
|||
|
|
super-intel.c:4360:29: error: writing 2 bytes into a region
|
|||
|
|
of size 0 [-Werror=stringop-overflow=]
|
|||
|
|
4360 | dev->vol.migr_state = 0;

cc1: note: destination object is likely at address zero

cc1: all warnings being treated as errors

make: *** [Makefile:232: super-intel.o] Error 1

reported, when GCC 14 is used. Return when dev is NULL, to avoid it.
