iommufd: Propagate allocation failure in iommufd_veventq_deliver_fetch()
When the kzalloc_obj() fails in iommufd_veventq_deliver_fetch(), it returns
NULL, falsely advertising to userspace that the queue is empty.
Propagate the -ENOMEM properly to the caller.
Fixes: e36ba5ab808e ("iommufd: Add IOMMUFD_OBJ_VEVENTQ and IOMMUFD_CMD_VEVENTQ_ALLOC")
