As reported by Coverity in GH #2253, stktable_data_ptr() usage in hlua_stktable_dump() func is potentially unsafe because stktable_data_ptr() may return NULL and the returned value is dereferenced as-is without precautions. In practise, this should not happen because some error checking was already performed prior to calling stktable_data_ptr(). But since we're using the safe stktable_data_ptr() function, all the error checking is already done within the function, thus all we need to do is check ptr against NULL instead to protect against NULL dereferences. This should be backported in every stable versions.
