vsprintf: reduce code size by avoiding extra check
No functional change, just refactor the code so that it avoid checking
"if (hi)" two times in a sequence, taking advantage of previous check made.
It also reduces code size:
text data bss dec hex filename

15710 0 8 15718 3d66 vsprintf.o (ex lib/lib.a-AFTER)
