gitweb: Fix error in git_patchest_body for file creation/deletion patch
 
$from_id, $to_id variables should be local per PATCH.

Fix error in git_patchset_body for file creation (deletion) patches,
where instead of /dev/null as from-file (to-file) diff header line, it
had link to previous file with current file name.  This error occured
only if there was another patch before file creation (deletion) patch.
