Subject: [PATCH][next] mwifiex: Fix fall-through warnings for Clang

From: "Gustavo A. R. Silva" <[email-masked]>
Date: Tue, 17 Nov 2020 10:09:58 -0600

In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple
warnings by explicitly adding multiple break statements instead of
letting the code fall through to the next case.
