Separate sending command to the fw from the event handling function to
simplify the disconnect flow and track the from_event flag correctly.

I don't get use of __acquires() and __releases() in this function. I see
similar pattern already in wil6210 but care to explain why this is
needed? I don't see the function even accessing tid_rx_lock so I'm very
confused.

I assume it is a copy / paste leftover that we missed in the code 
review.
We will remove it.

Actually I already removed the annotations from the pending branch and
no need to resend, it's faster that way. Please double check if you can,
unfortunately I cannot provide a direct link cgit doesn't show the new
commit yet.

In such a case you can go ahead and apply the patches without
"wil6210: ignore HALP ICR if already handled". I'll upstream its fixed 
version
in the next set of wil6210 patches.

Ok, I dropped "wil6210: ignore HALP ICR if already handled" and I'm
planning to apply the rest.
