Make fails while building the module in FreeSWITCH due to ISO C90 forbids mixed declarations

/usr/src/freeswitch-1.10.12/src/mod/applications/mod_audio_stream/mod_audio_stream.c: In function 'capture_callback':
/usr/src/freeswitch-1.10.12/src/mod/applications/mod_audio_stream/mod_audio_stream.c:35:17: error: ISO C90 forbids mixed declarations and code [-Werror=declaration-after-statement]

Fixed with the following change.

As per the instructions in README.md, you don't need to build the module alongside Freeswitch, but after Freeswitch is built. So I don't know if the fix will be accepted, even though it wouldn't hurt :)

Yes, the scripted build process works without any issues but still it's probably worth fixing to conform to ISO C90.
