Subject: [PATCH] lib/vsprintf: Do not handle %pO[^F] as %px

This patch avoids that gcc reports the following when building with W=1:

lib/vsprintf.c:1941:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
   switch (fmt[1]) {
   ^~~~~~

Fixes: ce4fecf1fe15 ("vsprintf: Add %p extension "%pOF" for device tree")
