[PATCH 1/3] fs: annotate implicit fall throughs

[Mathieu Malaterre]

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:

  fs/libfs.c:148:11: warning: this statement may fall through 
[-Wimplicit-fallthrough=]
  fs/libfs.c:150:7: warning: this statement may fall through 
[-Wimplicit-fallthrough=]
