Alexander Motin cb33306f41 Call ata_legacy() only once on attach and save it's result. Scanning PCI 
configuration registers (which are not going to change) on every interrupt
looks expensive, especially when interrupt is shared. Profiling shows me 3%
of time spent by atapci0 on pure network load due to IRQ sharing with em0.
