qcacmn: Skip updating OOR/2K jump BAR frames to H.W 

Currently error BAR frames are routed to host, but host
doesn't have complete information to check whether these
frames are valid and really action need to be taken or not.
If host updates H.W without validating SSN it is causing
window movement and REO HW aging timeout happening for
next set of RX packets and delay is induced.

To avoid RX packets delay skipping BAR update to H.W
