Rob Bradford f77f168532 virtio-devices: iommu: Roll back partial MAP and fix DETACH panic ...

A concurrent DETACH between the read-lock check and the write-lock
get_mut().unwrap() in MAP/UNMAP would panic the worker. Replace the
unwrap with a let-else.

A failure on a later endpoint in the per-endpoint MAP loop, or a
DETACH that races the missing-domain branch, must roll back the
external mappings already installed; otherwise domain.mappings
diverges from VFIO state.
