[PATCH 1/2] Fix error checking in Vitesse IRQ config

[Andy Fleming <afleming@freescale.com>]

phy_read() returns a negative number if there's an error, but the
error-checking code in the Vitesse driver's config_intr function
triggers if phy_read() returns non-zero.  Correct that.

I made a really stupid mistake in the 4 patches I sent out, earlier.  I
thought those patches had been tested, but they hadn't been.  This one
corrects a tiny error in the patch, and they have now been tested.  As before
this change can be pulled from:

http://opensource.freescale.com/pub/scm/linux-2.6-85xx.git netdev

Really, REALLY sorry about that.  I have been given a paper bag of appropriate
size and shape to fit over my head.
