Driver receives interface down/del virtual interface commands from kernel
with rtnl lock held. In driver, these commands will wait for SSR to be
completed. So in this case rtnl lock will be held for long time.
To avoid this, cache the north bound command received during SSR and
execute them in re-initialization sequence.

While the concepts of osif_sync started out as a simple set of APIs, it
ultimately evolved into its own full-fledge code module. While the
per-function documenation is present, high-level documentation for the
osif_sync code module as a whole was over looked. Add a high-level
description of the purpose of osif_sync in osif_sync.h

With the recent addition of osif_driver_sync APIs, DSC use is abstracted
behind a common interface. Migrate HDD to the new interface by updating
driver transitions to use the new APIs.

To bring OSIF driver synchronization in line with recent VDEV and PSOC
enhancements, add osif_driver_sync APIs. These allow for atomically
acquiring the driver synchronization context, and protecting various
call flows via DSC primitives.

Rename the osif_*_sync_create_with_trans() to a slightly more
appropriate osid_*_sync_create_and_trans(), to help convey the fact that
the transition does not end when the function returns.

Change I556e9d2833edd2bd26266496b6000347649c5fbe moved hdd_dsc to osif,
but retained the existing naming. Rename hdd_vdev_sync to a more
appropriate osif_vdev_sync, and address any remaining naming problems.

Change I556e9d2833edd2bd26266496b6000347649c5fbe moved hdd_dsc to osif,
but retained the existing naming. Rename hdd_psoc_sync to a more
appropriate osif_psoc_sync.

Move the contents of hdd_dsc to the new files added in osif/sync as part
of Ica94d32028d10d344294d6cc12d91a06efe1ab6c.

To better align with current organizational recommendations and allow
API use by os_if/nan, begin moving hdd_*_sync APIs to os_if. In step
one, create the new osif_sync file structure.
