virtio wants to read bitwise types from userspace using get_user. At the
moment this triggers sparse errors, since the value is passed through an
integer.
Fix that up using __force.

At the moment, if p and x are both tagged as bitwise types,
get_user(x, p) produces a sparse warning on many architectures.
This is because *p on these architectures is loaded into long

When typeof(*p) is a bitwise type (which is uncommon), such
