3.4-stable review patch. If anyone has any objections, please let me know.

commit fe020120cb863ba918c6d603345342a880272c4d upstream.
mwifiex driver supports 2x2 chips as well. Hence valid mcs values are 0 to 15. The check for mcs index is corrected in this patch.
For example: if 40MHz is enabled and mcs index is 11, "iw link" command would show "tx bitrate: 108.0 MBit/s" without this patch. Now it shows "tx bitrate: 108.0 MBit/s MCS 11 40Mhz" with the patch.
