If wlan is unloading when iperf is running, iperf
will call wmm select and check whether it's in
loading/unloading status, if yes, it will send the
following log to user space via wlan logging thread:
'Unloading/Loading in Progress. Ignore!!!';
These logs are printed too frequently, which will
cause watchdog bark.
To fix this issue, remove the log in:
wlan_hdd_validate_context();
