mm: prevent a warning when casting void* -> enum
I recently build the RISC-V port with LLVM trunk, which has introduced a
new warning when casting from a pointer to an enum of a smaller size.
This patch simply casts to a long in the middle to stop the warning. I'd
be surprised this is the only one in the kernel, but it's the only one I
saw.
