A reset callback is allowed to call functions disallowed in quiescent
state. However, the FLR reset path neglected to account for this
properly, causing an incorrect assert to be triggered if, for example,
vfu_sgl_put() is called. To fix this, make sure all reset paths go
through call_reset_cb().

Harmonize and rename the vfu_*sg() APIs to better reflect their functionality:
in our case, there is no mapping happening as part of these calls, they are
merely housekeeping for range splitting, dirty tracking, and so on.

Rename VFIO_DEVICE_STATE_XXXX defines as VFIO_DEVICE_STATE_V1_XXXX.
Upstream renamed these variable to be of the XXXX_V1_XXXX format and
switched an enum for VFIO_DEVICE_STATE_XXXX.

We explicitly identify the quiesce EBUSY case for msg(), letting us simplify the
handling of expected errno.
