mmc: cavium-octeon: destroy slot platform devices on remove

Browse source

octeon_mmc_probe() creates host->slot_pdev[i] with
of_platform_device_create(), while octeon_mmc_remove() does not destroy
the child platform devices.

The probe failure path removes each MMC slot and destroys its associated
platform device, but the normal remove path only removes the MMC slot.
As a result, the child platform devices remain registered after the
Octeon MMC controller is removed.

Destroy each slot platform device during removal after cleaning up the
corresponding MMC slot, matching the probe failure cleanup path.

This issue was found by manual code inspection.
