Patch for e100 on my z505je

[Pete Zaitcev]

Jeff,

I tried Marcelo's 2.4.21-pre2 and the driver fails the self-test,
then dies in an unserviced interrupt storm. An obvious patch
seems to fix the problem here.

Amazingly enough, the driver works in RH 2.4.18-14 (e100 2.1.6-k1),
but if I take the same 2.1.6-k1 and implant it into Marcelo tree,
everything dies as before. Something is fishy here.
