As part of HOLB monitoring, uc will clear the HOLB discard if
it was set as part of HOLB monitoring or it can clear if
peripheral recovers just before receiving HOLB_DEL command.
Make change to set HOLB discard back if it was intended to be
configured from AP as part of disconnect scenarios.

When ssr happen in middle of egress ioctl, only tx pipe is setup
and the current state in teardown cannot handle it.
The fix is to add state for tx/rx setup separately.

If at the same time USB disconnection is in progress, there

driver. Make changes to add proper checks to handle the scenario

In case napi_schedule() called before the net_dev_init(),

the napi_schedule() call will cause null pointer dereference.
This change sets dependency on passing the subsys_init for
the napi_schedule() calls.

Some init operations may cause race within initcall.
To avoid that race, those operations have to be postponed
till later initcall (fs_initcall for now).
This change introduces the ipa_late_init module, which (for now)
will take care of RMNET platform driver registration,
which would have caused race with core net_dev,
if was called in the subsys_initcall.
