[XFS] Remove the xlog_ticket allocator
The ticket allocator is just a simple slab implementation internal to the log. It requires the icloglock to be held when manipulating it and this contributes to contention on that lock. Just kill the entire allocator and use a memory zone instead. While there, allow us to gracefully fail allocation with ENOMEM.
