    vhost: add max_mem_regions module parameter · c9ce42f7

    it became possible to use a bigger amount of memory
    slots, which is used by memory hotplug for
    registering hotplugged memory.
    However QEMU crashes if it's used with more than ~60
    pc-dimm devices and vhost-net enabled since host kernel
    in module vhost-net refuses to accept more than 64
    memory regions.
    
    Allow to tweak limit via max_mem_regions module paramemter
    with default value set to 64 slots.
