Commit 7fd89e49 ("bluetooth: Try to reconnect SCO") introduces a call
pa_msleep but failed to include the header, resulting in a:
../pulseaudio/src/modules/bluetooth/backend-native.c: In function ‘sco_acquire_cb’: ../pulseaudio/src/modules/bluetooth/backend-native.c:336:17: warning: implicit declaration of function ‘pa_msleep’ [-Wimplicit-function-declaration] 336 | pa_msleep(300); | ^~~~~~~~~
(Un)fortunately this implicit declaration gets resolved at link-time, otherwise the issue would have been caught sooner.
Fixes: 7fd89e49 ("bluetooth: Try to reconnect SCO")
