iommufd: Add three missing structures in ucmd_buffer 

struct iommu_ioas_copy, struct iommu_option and struct iommu_vfio_ioas are
missed in ucmd_buffer. Although they are smaller than the size of
ucmd_buffer, it is safer to list them in ucmd_buffer explicitly.

Fixes: aad37e71d5 ("iommufd: IOCTLs for the io_pagetable")
Fixes: d624d6652a ("iommufd: vfio container FD ioctl compatibility")
