lib/vsprintf.c: document more vsnprintf extensions
These were added in
9ac6e44 (lib/vsprintf.c: add %pU to print UUID/GUIDs)
c7dabef (vsprintf: use %pR, %pr instead of %pRt, %pRf)
8a27f7c (lib/vsprintf.c: Add "%pI6c" - print pointer as compressed ipv6 address)
4aa9960 (printk: add %I4, %I6, %i4, %i6 format specifiers)
dd45c9c (printk: add %pM format specifier for MAC addresses)
but only added comments to pointer() not vsnprintf() that is refered to by
printk's comments.
