ide/ide-cs: fix order of releasing resources

ide_detach() called first ide_release() and then release_region(). This
produced the following warnings:

  Trying to free nonexistent resource <000000000000c10e-000000000000c10e>
  Trying to free nonexistent resource <000000000000c100-000000000000c107>

This is true, because the callchain inside ide_release() is:

  ide_release -> pcmcia_disable_device -> pcmcia_release_io

So, the whole io-block is already gone for release_region(). To fix
this, just swap the order of releasing (and remove the now obsolete
shadowing).

- release resources in ide_release() to fix ordering of events
- remove stale FIXME note while at it
