[RFC PATCH 02/30] lib/string_helpers: Drop space in string_get_size's output

[Suren Baghdasaryan <surenb@xxxxxxxxxx>]

From: Kent Overstreet <kent.overstreet@xxxxxxxxx>

Previously, string_get_size() outputted a space between the number and
the units, i.e.
  9.88 MiB

This changes it to
  9.88MiB

which allows it to be parsed correctly by the 'sort -h' command.
