    Revert "wifi: mwifiex: Fix HT40 bandwidth issue."
    
    This reverts commit 4fcfcbe ("wifi: mwifiex: Fix HT40 bandwidth
    issue.")
    
    That commit introduces a regression, when HT40 mode is enabled,
    received packets are lost, this was experience with W8997 with both
    SDIO-UART and SDIO-SDIO variants. From an initial investigation the
    issue solves on its own after some time, but it's not clear what is
    the reason. Given that this was just a performance optimization, let's
    revert it till we have a better understanding of the issue and a proper
    fix.
