iwlwifi: mvm: fix reorder timer re-arming

Browse Source 
commit 5351f9ab254c30d41659924265f1ecd7b4758d9e upstream.

When NSSN is behind the reorder buffer due to timeout
the reorder timer isn't getting re-armed until NSSN
catches up. Fix it.

Fixes: 0690405fef29 ("iwlwifi: mvm: add reorder timeout per frame")
