Revert "wifi: mwifiex: Fix HT40 bandwidth issue."
commit 570896604f47d44d4ff6882d2a588428d2a6ef17 upstream.
This reverts commit 4fcfcbe45734 ("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.
