audio/ossaudio: Fix compiler warning with -Wshadow

The "err" variable is only used twice in this code, in a very local fashion of first assigning it and then checking it in the next line. So there is no need to declare this variable a second time in the innermost block, we can re-use the variable that is declared at the beginning of the function. This fixes the compiler warning that occurs with "-Wshadow".
