Race condition between ifconfig and ipa uc event handler thread.
While ifconfig thread creating vdev1, the vdev is locked, ipa uc
event handler thread tries to lock psoc, becomes failed for 1
dev locked, gets error EAGAIN but doesn't try again. IPA uc
event is abandoned without handling.
Fix:
IPA uc event handling can't be abandoned but can be blocked
since it is called in separated work thread, block DSC API
should be used here.
Blocked Operation and Transition have no much difference in DSC,
and they need block each other too, should share same
completion and queue, can share same API.
With WDI 3.0 over GSI, WDI control event is not needed. Therefore
provide a wrapper API for wlan_ipa_uc_send_wdi_control_msg().
