ath5k: correct interrupt storm warning
Bob Copeland [Tue, 28 Apr 2009 02:18:10 +0000 (22:18 -0400)]
Ben Greear points out that the "too many interrupts" message will
never print in the intended case since the interrupt counter
will be -1 after the loop.  Change it to pre-decrement so it will
be 0 on the thousandth iteration.
