Subject: [PATCH] drivers: stm: correct the index in master array release
It would be broken if stm_data->sw_start isn't zero, because that
stp_master_free() get the 'master' with __stm_master()/stm_master(),
in which the masterID is the second input parameter minus
stm_data->sw_start. So freeing STM masters has to start from
stm_data->sw_start.
