vhost: fix VHOST_GET_BACKEND_FEATURES ioctl request definition
The _IOC_READ flag fits this ioctl request more because this request
actually only writes to, but doesn't read from userspace.
See NOTEs in include/uapi/asm-generic/ioctl.h for more information.
Fixes: 429711aec282 ("vhost: switch to use new message format")
