gnttab: don't use possibly unbounded tail calls
There is no guarantee that the compiler would actually translate them
to branches instead of calls, so only ones with a known recursion limit
are okay:
- __release_grant_for_copy() can call itself only once, as
__acquire_grant_for_copy() won't permit use of multi-level transitive
grants,
- __acquire_grant_for_copy() is fine to call itself with the last
argument false, as that prevents further recursion,
- __acquire_grant_for_copy() must not call itself to recover from an
observed change to the active entry's pin count
This is part of XSA-226.
