qseecom: use scm_call2 for shutdown appLA.UM.7.8.r1-06900-SDM710.0
Unlike scm_call2, __qseecom_scm_call2_locked() will unlock
app_access_lock to let another qseecom thread work. But this
mutex should not be released for shutdown app thread to
prevent another thread accessing the resource that is freed
by shutdown thread. So change to use scm_call2 for this cmd.
