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 warnings:

  lib/cmdline.c:137:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
  lib/cmdline.c:140:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
  lib/cmdline.c:143:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
  lib/cmdline.c:146:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
  lib/cmdline.c:149:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
