ath6kl: wmi: fix an error code in ath6kl_wmi_sync_point() 

[ Upstream commit fd6729ec534cffbbeb3917761e6d1fe6a412d3fe ]

This error path is unlikely because of it checked for NULL and
returned -ENOMEM earlier in the function.  But it should return
an error code here as well if we ever do hit it because of a
race condition or something.
