[PATCH] git svn: catch lack of upstream info for dcommit earlier

[Thomas Rast <trast@student.ethz.ch>]

Since 711521e 'git svn dcommit' attempts to use the upstream
information to determine the SVN URL, before it verifies that it even
found an upstream.  Move up the corresponding check.

After resolving the problem on IRC, here's the fix to avoid the
