avutil/slicethread: Remove NULL pointer check when freeing

avpriv_slicethread_free() is one of our functions that takes
a pointer to a pointer and resets the pointer when done.
It is legal for such functions to be passed a pointer to a NULL
pointer, yet passing a NULL pointer would be insane and should
not be tolerated.
