Subject[PATCH 2/3] security: keys: annotate implicit fall throughs
Date
There is a plan to build the kernel with -Wimplicit-fallthrough and
these places in the code produced warnings (W=1). Fix them up.

This commit remove the following warning:

security/keys/process_keys.c:380:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
security/keys/process_keys.c:404:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
security/keys/process_keys.c:424:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
