qcacmn: Runtime PM packets tagging after wow suspend

Browse Source 
qcacld-2.0 to qcacmn propagation.

Don't Tag Non-WoW packets as Runtime PM packets after
wow suspend. Some WMI Commands can be send in Runtime
PM context and MC thread context. Packets coming via
MC Thread Context can be tagged as Runtime PM packets
when runtime pm in progress.

Packets should be tagged in the same caller context to
avoid any race condition. Being stability issue, addressing
this issue by not tagging any non-wow commands as runtime pm
after wow suspend. This will ensure all the non-wow packets
coming after wow_suspend flag is set as non runtime pm packets
and will trigger a runtime resume.
