core: ofnode: do not assert if node not valid in ofnode_get_name()

Browse Source 
In some case with LIVE DT, some node always not valid, or not have
a valid name, eg. blk driver add by mmc.
Return fail instead of Assert for this kind of ofnode, and this
help with assert happen from time to time when of_live is enabled
and DEBUG is enabled.
