[PATCH] submodule: add newline on invalid submodule error

[Emily Shaffer <emilyshaffer@google.com>]

Since 'err' contains output for multiple submodules and is printed all
at once by fetch_populated_submodules(), errors for each submodule
should be newline separated for readability. The same strbuf is added to
with a newline in the other half of the conditional where this error is
detected, so make the two consistent.
