bcache: fix incorrect pointer check

Browse Source 
With commit b44db5d1a7ecc2e8e3cef0852c4397b64ddf0a09
needs to check allocated pointer for failed malloc().

Existing check was actually no checking anything so failing
malloc here would result in segfault (although with very
low chance to ever happen).
