The FP_LOCK_SLOTS_PER_BACKEND macro looks like a constant, but it depends on the max_locks_per_transaction GUC, and thus can change. This is non-obvious and confusing, so make it look more like a function by renaming it to FastPathLockSlotsPerBackend(). While at it, use the macro when initializing fast-path shared memory, instead of using the formula.
