wl1271: Fix keep-alive related command error

The firmware does not like the host configuring the keep-alive after it has
been once configured after a join-operation. Instead, it will complain about
invalid parameters, which do not break functionality, but do not look nice
in the syslog either.

This patch prevents the complaints by only configuring the keep-alive once
for an association, after the first time join is performed with the correct
bssid.
