Revert recent change to RequestNamedLWLockTranche(). Commit 38b602b028 modified this function to allocate enough space for MAX_NAMED_TRANCHES (256) requests, which is likely far more than most clusters need. This commit reverts that change so that it first allocates enough space for only 16 requests and resizes the array when necessary. While at it, remove the check for too many tranches from this function. We can now rely on InitializeLWLocks() to do that check via its calls to LWLockNewTrancheId() for the named tranches.
