audioamplify: Don't declare a loop index static

Browse source 
The previous patch to add support for additional sample formats possibly
introduced a reentrancy bug:  a variable used for a loop index was declared
static.  This patch fixes that, and also adds a "/* *INDENT-ON* */" annotation
following the macro block.  (I don't know what the annotation is for, but the
adder, where I copied this from, has it).
