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

[Bart Van Assche]

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")
