Remove unused variable in drivers/dma/ioatdma.c

Hi,

I found this in an `allyesconfig' build:

CC drivers/dma/ioatdma.o
drivers/dma/ioatdma.c: In function #ioat_dma_free_chan_resources#:
drivers/dma/ioatdma.c:247: warning: unused variable #chanctrl#

This exists as a patch in -mm for what seems like months.

I can't believe this one-liner hasn't been merged yet, it's silly.

I was even chastised at one point for merging it into my net-2.6.24 tree :-)
