bnxt_en: Remove locking around txr->dev_state

Browse Source 
commit cbce91cad4ee39070bf3c7873767194e4be88e16 upstream.

txr->dev_state was not consistently manipulated with the acquisition of
the per-queue lock, after further inspection the lock does not seem
necessary, either the value is read as BNXT_DEV_STATE_CLOSING or 0.
