[PATCH 3/4] bootm: delete initrd reserve entry on bootm_boot return

[Ahmad Fatoum]

Repeating dry runs with an initrd will eventually lead to exhausting the
reserve memory entries as OF_MAX_RESERVE_MAP is only 16.

Make sure to clean up after ourselves if bootm_boot returns without
actually booting.
