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".
