e1000: avoid null pointer dereference on invalid stat type
[ Upstream commit 5983587c8c5ef00d6886477544ad67d495bc5479 ]
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.
