[PATCH v5 05/12] vsprintf: reduce code size by avoiding extra check

["André Goddard Rosa" <andre.goddard@gmail.com>]

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
  15726       0       8   15734    3d76 vsprintf.o (ex lib/lib.a-BEFORE)
  15710       0       8   15718    3d66 vsprintf.o (ex lib/lib.a-AFTER)
