ide: fix generic_ide_suspend/resume Oops
This patch fixes a regresion introduced by commit 0998d063 (device-core: Ensure
drvdata = NULL when no driver is bound).
Suspend oopses in generic_ide_suspend() because dev_get_drvdata()
returns NULL (dev->p->driver_data == NULL) and this function is not
prepared for this.
Fix is based on Alan Stern's suggestion.
