x86/mm: Fix operator associativity bug in mm-locks.h

In an order-enforcing wrapper for an "external" recursive lock,
we aim to increment/decrement a recurse count and only update the
lock ordering on zero counts.

Unfortunately we incrementing/decrementing the pointer to the
recurse count, rather than the count itself.
