Ignore BIOS disk geometry for EFI bootsteap

[Emmanuel Dreyfus <manu%netbsd.org@localhost>]

Hello

I just encountered a boostrap crash on a recenrt mac. The machine seems to
only be able to boot over EFI, and it crashes inside bi_getbiosgeom() 
because it gets garbage data. 

Is BIOS disk geometry of any use when booting over EFI? The machine boots
fine with the change below, does anyone foresee any trouble if I commit it?
