svolume.orc: avoid parameter loading undefined behaviour

Browse source 
In some cases, depending on the instruction that performs the load, orc
ignores the size of the parameter when loading it for the first time.
Explicitly load the parameter into a temp to make sure it is loaded
correctly, like we do for the 2ch case.

See https://bugzilla.gnome.org/show_bug.cgi?id=742271
