mac80211: fix possible null-pointer de-reference
This patch not only fixes a null-pointer de-reference
that would be triggered by a PLINK_OPEN frame with mis-
matching/incompatible mesh configuration, but also
responds correctly to non-compatible PLINK_OPEN frames
by generating a PLINK_CLOSE with the right reason code.
The original bug was detected by smatch.

error: we previously assumed 'sta' could be null.
