[PATCH iproute2-next v2 4/7] lib: sprint_size(): Uncrustify the code a bit

[Petr Machata <me@pmachata.org>]

Ideally this and the rate printing would both be converted to a common
helper, but unfortunately the two format differently and this would break
tests and scripts out there. So just make the code look less like a wad of
hay.

Notes:
    v2:
    - This patch is new. It addresses a request from Stephen Hemminger to
      clean up the sprint_size() function.
