newlib: fix uninitialized character count being used when printing float without "_printf_float" being linked
Patch fixes wrong number of written characters being returend from 'printf'
family of functionsx when '_printf_float' is not linked (nano.specs). If user
tries to print a floating point number anyway, returned number of written
characters is not correct. For example in
printf("%d%f", 1, 1.0);
should return 1, but actaully returns 2.
