Merge patch series "boot: image-fdt: Restore suppression of irrelevant ERROR message"

Jonas Karlman <[email protected]> says:

This series changes the returned error code for lmb_alloc_mem() and
lmb_free() may return to help restore suppression of the verbose ERROR
messages when FDT memreserve and reserved-memory is being processed.
