Zheng Wang f67b0e3081 bcache: Fix __bch_btree_node_alloc to make the failure behavior consistent
commit 80fca8a10b upstream.

In some specific situations, the return value of __bch_btree_node_alloc
may be NULL. This may lead to a potential NULL pointer dereference in
caller function like a calling chain :
btree_split->bch_btree_node_alloc->__bch_btree_node_alloc.

Fix it by initializing the return value in __bch_btree_node_alloc.
