[PATCH 1/2] cxgb4: smt: Add lock for atomic_dec_and_test

The atomic_dec_and_test() is not safe because it is outside of locks. Move the locks of t4_smte_free() to its caller, cxgb4_smt_release() to protect the atomic decrement. Fixes: 3bdb376e6944 ("cxgb4: introduce SMT ops to prepare for SMAC rewrite support") Signed-off-by: Chuhong Yuan ---
