Niklas Cassel da5bd0e7e8 ata: libata-core: Fix double free on error
commit ab9e0c529eb7cafebdd31fe1644524e80a48b05d upstream.

If e.g. the ata_port_alloc() call in ata_host_alloc() fails, we will jump
to the err_out label, which will call devres_release_group().
devres_release_group() will trigger a call to ata_host_release().
ata_host_release() calls kfree(host), so executing the kfree(host) in
ata_host_alloc() will lead to a double free:

Ensure that we will not call kfree(host) twice, by performing the kfree()
only if the devres_open_group() call failed.
