[PATCH] hw/net/can: Add missing fallthrough statements

[Thomas Huth <thuth@redhat.com>]

Add fallthrough annotations to be able to compile the code without
warnings when using -Wimplicit-fallthrough in our CFLAGS. Looking
at the code, it seems like the fallthrough is indeed intended here,
so the comments should be appropriate.
