BACKPORT: FROMLIST: mwifiex: don't print SSID to logs
There are a few reasons not to dump SSIDs as-is in kernel logs:
1) they're not guaranteed to be any particular text encoding (UTF-8,
ASCII, ...) in general
2) it's somewhat redundant; the BSSID should be enough to uniquely
identify the AP/STA to which we're connecting
3) BSSIDs have an easily-recognized format, whereas SSIDs do not (they
are free-form)
4) other common drivers (e.g., everything based on mac80211) get along
just fine by only including BSSIDs when logging state transitions
Additional notes on reason #3: this is important for the
privacy-conscious, especially when providing tools that convey
kernel logs on behalf of a user -- e.g., when reporting bugs. So for
example, it's easy to automatically filter logs for MAC addresses, but
it's much harder to filter SSIDs out of unstructured text.
