mac80211: add patch for mwifiex to fix cryptic errors/warnings 

In Turris MOX SDIO card [1], which uses Marvell 88W997 and its driver
mwifiex, you might get cryptic messages, which are not helpful to use.
@pali created patch, which improves messages by the driver and he will
send this to Linux kernel soon.

Before:
[   81.026156] mwifiex_sdio mmc1:0001:1: CMD_RESP: cmd 0x20 error, result=0x1

After:
[   15.784018] mwifiex_sdio mmc1:0001:1: CMD_RESP: cmd RF_ANTENNA (0x20) error, result=0x1

Subject: [PATCH] mwifiex: Print stringified name of command in error log
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Failed hex command number in error log is hard to understand.
So add also more human readable stringified command name into error log.
