IOV regression testing led to discovery of a minor issue + possibly race
in IOV flows:
a. Malicious indications in VF-database on PF-side get cleared during
FLR flows - but not when disabling SRIOV. At least in Linux if you
disable IOV while having a malicious VF you wouldn't be able to
clear the indication as driver would prevent from initializing it.
b. Possible race during PF response to VF - the channel is made ready
only after sending the rc via dmae to VF. It's possible due to
context switch at end of DMAE [when releasing Mutex] that VF would
start running and send another message prior to PF clearing the
channel, making the FW consider that VF to be malicious.
This patch fixes that by
- clearing the indication even if we're only going to disable VF
- resetting the channel to ready before PF copies the rc to the VF, PF
can then continue and send an additional message
