ide-floppy: use drive->capacity64 for caching current capacity
* Use drive->capacity64 for caching current capacity.
* Switch ide_floppy_capacity() to use drive->capacity64.
* Call set_capacity() in idefloppy_open() and ide_floppy_probe()
instead of ide_floppy_get_capacity().
There should be no functional changes caused by this patch.
