GC error encountered in Android runtime environment

https://github.com/HaxeFoundation/hashlink/commit/21ede72a8abbc39b71c3c3607eca7c8a5d688d28#r77274896

This is the key cause of the problem.

And i chaneg it:
```c
pextra *e = extra_pages, *prev = NULL;
while( e ) {
__android_log_print(ANDROID_LOG_VERBOSE, "SDL", "page_ptr=%d ptr=%d", e->page_ptr,ptr);
if( e->page_ptr == ptr ) {
if( prev )
prev->next = e->next;
else
extra_pages = e->next;
munmap(e->base_ptr, size + EXTRA_SIZE);
return;
}
prev = e;
e = e->next;
}
munmap(ptr,size);
```

Crash log:
