    ath11k: Avoid REO CMD failed prints during firmware recovery
    
    [ Upstream commit 0ab52b2bd7be8fd49c8ade7703c1faa15359c6c5 ]
    
    Currently when firmware recovery is in progress, we do not queue REO
    commands to the firmware, instead -ESHUTDOWN will be returned to the
    caller leading to a failure print on the console. The REO command in
    the problem scenario is sent for all tids of a peer in which case we
    will have 16 failure prints on the console for a single peer. For an
    AP usecase, this count would be even higher in a worst case scenario.
    Since these commands are bound to fail during firmware recovery, it
    is better to avoid printing these failures and thereby avoid message
    flooding on the console.
