[PATCH] omapfb: add one more "fallthrough" statement

From: Arnd Bergmann <arnd@arndb.de>

clang warns about one missing fallthrough that gcc ignores:

drivers/video/fbdev/omap/omapfb_main.c:1558:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]

Add it here as well.
