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=]
