… configured

Root cause:
- In handlePortTableUpdate, refreshPgsFromPort is called if admin status is updated even if the speed is not configured.
  This is reasonable because the port can be configured as headroom override and the profile should be applied in that case.
- However, the port's state is set to PORT_READY in refreshPgsForPort regardless whether speed is configured, which is not correct.
  This is should be avoided and PORT_READY should be set by caller if necessary
Fix:
- Don't set port's state to READY in refreshPgsForPort
- Explicitly set port's state to READY in handlePortState. This has been done by all other callers.
