In mpt3sas_base_clear_st() function smid value is reseted in wrong line, i.e. driver should reset smid value to zero after decrementing chain_offset counter in chain_lookup table but in current code, driver is resetting smid value before decrementing the chain_offset counter. which we are correcting with this patch.
