alsa-tools: Fix compiling with clang

Fixed a linking error occurring when building with clang, where a
function reference is emitted but function is not since its marked as
inline, making it static inline gives better opportunity to compiler to
compile it

+The function is not used in any other file, its better to make it static
+inline so compiler has a better chance of optimizing here
