[PATCH] ide: fix PCI modules oops

Forward-port of 2.4.21-ac4 patch by Wilfried Weissmann.

ide_get_or_set_dma_base() may be called via ide_setup_pci_device()
when a PCI controller module is loaded.  However, it is defined with __init
and the function is called when its memory is already deallocated.
