[PATCH master] bootm: ignore global.bootm.initrd if unavailable

[Ahmad Fatoum]

The bootm.initrd* variables are only available if CONFIG_BOOTM_INITRD is
enabled, but we were saving and attempting to restore them
unconditionally.

Fix that to avoid confusing warnings on systems without initrd support
compiled in.

Fixes: 926985a74ee0 ("bootm: don't clobber global.bootm. variables after script boot fails")
