ioat: preserve chanctrl bits when re-arming interrupts
The register write in ioat_dma_cleanup_tasklet is unfortunate in two
ways:
1/ It clears the extra 'enable' bits that we set at alloc_chan_resources time
2/ It gives the impression that it disables interrupts when it is in
fact re-arming interrupts
[ Impact: fix, persist the value of the chanctrl register when re-arming ]
