firmware: qcom: scm: Fix __scm and waitq completion variable initialization
It is possible qcom_scm_is_available() gives wrong indication that if __scm is initialized while __scm->dev is not and similar issue is also possible with __scm->waitq_comp. Fix this appropriately by the use of release barrier and read barrier that will make sure if __scm is initialized so, is all of its field variable.
