ide: mask interrupt in ide_config_drive_speed() 

Apparently, there is no sense in unmasking IRQ on the controller when you call
disable_irq_nosync() before doing this, set the nIEN bit afterwards, and then
unmask IRQ again after the command completion, hence 0 passed to SELECT_MASK()
before issuing the command in ide_config_drive_speed() is probably just a typo.
