[PATCH 001/141] afs: Fix fall-through warnings for Clang

From: Gustavo A. R. Silva
Date: Fri Nov 20 2020 - 13:24:23 EST


In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple
warnings by explicitly adding multiple fallthrough pseudo-keywords
in places where the code is intended to fall through to the next
case.
