msm: kgsl: Correct the number of voltage levels for a rail

In rpmh_arc_cmds(), len got from cmd_db_get_aux_data_len() is
twice the number of voltage levels. Hence, arc->num which
represents voltage levels for a rail, should be evaluated by
traversing arc->val table upto (len >> 1) instead of
len or MAX_GX_LEVELS.
