Summary
bcache: Fix __bch_btree_node_alloc to make the failure behavior consistent
Details

In the Linux kernel, the following vulnerability has been resolved:

bcache: Fix _bchbtreenodealloc to make the failure behavior consistent

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

Fix it by initializing the return value in _bchbtreenodealloc.
