ISSUE DESCRIPTION
We have discovered two bugs in the code unmapping grant references.
* When a grant had been mapped twice by a backend domain, and then
unmapped by two concurrent unmap calls, the frontend may be informed
that the page had no further mappings when the first call completed rather
than when the second call completed.
* A race triggerable by an unprivileged guest could cause a grant
maptrack entry for grants to be "freed" twice. The ultimate effect of
this would be for maptrack entries for a single domain to be re-used.
IMPACT
For the first issue, for a short window of time, a malicious backend
could still read and write memory that the frontend thought was its
own again. Depending o
