Subject: [PATCH 0/2] virtio: add gfp_t parameter to add_buf

We need to allocate memory to post indirect buffers,
and sometimes drivers do this from a thread context,
so it helps to pass in a gfp_t parameter.

To avoid churn changing all drivers, add a new API
with a _gfp prefix, and make the old call lacking
gfp_t an inline wrapper.
