inform_shopfloor: remove waiting for interface ready

Previously we will wait for interface ready before posting. However,
different board may have different interface name, e.g. eth0, wan0, making
it difficult to check the correct one. This check can be removed. The
posting can be retried to avoid the problem.

BUG=None
TEST=None
