system/iommufd: Use uint64_t type for IOVA mapping size
The 'ram_addr_t' type is described as: a QEMU internal address space that maps guest RAM physical addresses into an intermediate address space that can map to host virtual address spaces. This doesn't represent well an IOVA mapping size. Simply use the uint64_t type.
