Tuong Lien 049fa17f7a Revert "tipc: Fix potential tipc_node refcnt leak in tipc_rcv" ... This reverts commit de05842076. There is no actual tipc_node refcnt leak as stated in the above commit. The refcnt is hold carefully for the case of an asynchronous decryption (i.e. -EINPROGRESS/-EBUSY and skb = NULL is returned), so that the node object cannot be freed in the meantime. The counter will be re-balanced when the operation's callback arrives with the decrypted buffer if any. In other cases, e.g. a synchronous crypto the counter will be decreased immediately when it is done. Now with that commit, a kernel panic will occur when there is no node found (i.e. n = NULL) in the 'tipc_rcv()' or a premature release of the node object. This commit solves the issues by reverting the said commit, but keeping one valid case that the 'skb_linearize()' is failed.
