wil6210: missing reinit_completion in wmi_call
The code in wmi_call uses the wil->wmi_call completion structure to wait for a reply. In some scenarios, complete was called twice on the completion structure. This happened mainly with a disconnect event which can arrive both unsolicited and as a reply to a disconnect request. In this case the completion structure was left marked as "done" and the next wmi_call returned immediately with a corrupted reply buffer. This caused unexpected results including crashes. Fix this by adding the missing call to reinit_completion.
