floppy: Clean up Check Interrupt Status code.

Don't run the Check Interrupt Status command from the floppy hardware
interrupt handler.  Instead, run it where it is needed - after
controller startup and after a recalibration command.  Also, use
floppy_pio() to issue the command instead of open coding it.
