ide: check drive->present in ide_get_paired_drive()
* Change ide_get_paired_drive() to return NULL if peer device
is not present and update all users accordingly.
While at it:
* ide_get_paired_drive() -> ide_get_pair_dev()
* Use ide_get_pair_dev() in cs5530.c, sc1200.c and via82cxxx.c.
There should be no functional changes caused by this patch.
