ide: Make it explicit that ide_create_drive() can't fail

All callers of ide_create_drive() ignore its value.  Currently
harmless, because it fails only when qdev_init() fails, which fails
only when ide_drive_initfn() fails, which never fails.

Brittle.  Change it to die instead of silently ignoring failure.
