[PATCH] "3c59x collision statistics fix" fix

The pre-2.6.16 patch "3c59x collision statistics fix" accidentally caused
vortex_error() to not run iowrite16(TxEnable, ioaddr + EL3_CMD) if we got a
maxCollisions interrupt but MAX_COLLISION_RESET is not set.

Thanks to Pete Clements <clem@clem.clem-digital.net> for reporting and testing.
