msm: ipa: Fix to set holb discard

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.
