e1000: avoid null pointer dereference on invalid stat type
Currently if the stat type is invalid then data[i] is being set either by dereferencing a null pointer p, or it is reading from an incorrect previous location if we had a valid stat type previously. Fix this by skipping over the read of p on an invalid stat type.
