IOATDMA: fix section mismatches

Rename struct pci_driver data so that false section mismatch warnings won't
be produced.

Sam, ISTM that depending on variable names is the weakest & worst part of
modpost section checking.  Should __init_refok work here?  I got build
errors when I tried to use it, probably because the struct pci_driver probe
and remove methods are not marked "__init_refok".

WARNING: drivers/dma/ioatdma.o(.data+0x10): Section mismatch: reference to .init.text: (between 'ioat_pci_drv' and 'ioat_pci_tbl')
WARNING: drivers/dma/ioatdma.o(.data+0x14): Section mismatch: reference to .exit.text: (between 'ioat_pci_drv' and 'ioat_pci_tbl')
