    [NTOSKRNL] Don't dereference VACB when allocating its memory area fails
    
    This avoids performing a double-free (even though that's hidden by the
    fact we use lookaside allocations for VACB), and it avoids freeing
    a memory address at an uninitialized address.
    We don't care about references here, the VACB was just allocated, never
    linked and we're its only user.
