[PATCH 12/13] treewide: Use fallthrough pseudo-keyword

[Sebastian Huber]

From: "Gustavo A. R. Silva" <gustavoars at kernel.org>

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.
