Use vmem_alloc() for zfs_ioc_pool_get_history()

The default buffer size when requesting history is 128k.  This
is far to large for a kmem_alloc() so instead use the slower
vmem_alloc().  This path has no performance concerns and the
buffer is immediately free'd after its contents are copied to
the user space buffer.
