audit: no leading space in audit_log_d_path prefix
audit_log_d_path() injects an additional space before the prefix, which serves no purpose and doesn't mix well with other audit_log*() functions that do not sneak extra characters into the log. Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Eric Paris <eparis@redhat.com>
