much smaller bdrv_co_invalidate_cache() that basically just calls into
the driver, would that solve the problem?

bdrv_co_invalidate_cache is special: it is an I/O function,
but uses the block layer permission API, which is GS.
Because of this, we can assert that either the function is
being called with BQL held, and thus can use the permission API,
or make sure that the permission API is not used, by ensurin
