hv: vtd: fix the pre-allocated context table number

In current code, there is an out of range access to the array buses defined in struct struct context_table.
This patch defines CONFIG_IOMMU_BUS_NUM to replace CONFIG_IOMMU_INIT_BUS_LIMIT, which is clearer.
CONFIG_IOMMU_BUS_NUM equals to (CONFIG_IOMMU_INIT_BUS_LIMIT + 1).
