Currently host driver does not wait for uptree operations in dsc
before it starts vdev transitios, which may lead to memory domain
mismatch.
For example, if modules are closed because of idle shutdown, memory
domain in host driver will be init domain and at that time if some
psoc ops starts, memory allocated as part of this ops will be
allocated in init domain and if at the same time if vdev up starts
which will trigger the vdev trans and will start the modules and change
the memory domain to active domain, now when the memory allocated as
part of psoc operation is released on psoc ops completion will be
released in the active domain which leads the memory domain mismatch.
In current issue, host driver closes the modules because of idle
shutdown and changes the memory domain to init domain, now host driver
receives get features vendor command and starts psoc operation which
allocates memory in init domain, while this psoc operation is still in
progress, host driver receives interface create which starts vdev
operation and changes the memory domain to active domain as part of
start modules. Now, when ongoing psoc operation completes, it
releases the momory in active domain, which results in memory
domain mismatch.
To fix this issue, before starting vdev transition, add wait for uptree
operations in dsc tree, which includes wait for psoc operations and
driver operations as this issue is possible with the driver operations
as well.
