HAMMER VFS - Ensure sufficient free memory is available before large allocation
* The HAMMER rebalancing code can be a heavy user of kernel memory when
collecting B-Tree nodes to rebalance.
Call the new vm_wait_nominal() function before allocating said memory
in an attempt to avoid VM/VFS deadlocks when memory is low.
