[PATCH] thread-win32: Implement pa_thread_free_nojoin()

[tanu.kaskinen@xxxxxxxxxxxxxxx (Tanu Kaskinen)]

This fixes a build error with mingw32:

pulsecore/.libs/libpulsecommon_4.99_la-lock-autospawn.o: In function `unref':
/home/abuild/rpmbuild/BUILD/pulseaudio-4.99.2/src/pulsecore/lock-autospawn.c:123: undefined reference to `pa_thread_free_nojoin'
collect2: error: ld returned 1 exit status

pa_thread_free_nojoin() was initially only implemented for the pthread
based pa_thread backend, because it was incorrectly assumed that
autospawning (the only user of pa_thread_free_nojoin()) is not used on
Windows.
