userspace/wrsw_hal: don't run fsm at the first check of a link state

Running fsm_generic_run in hal_port_state_fsm_init_all delays setting
shmemState as HAL_SHMEM_STATE_INITITALIZED, which causes the timeout
(and exit) at the startup of wrsw_rtud. wrsw_rtud is restarted by
monit. However, wrs_vlans is run only once by init and is not able to setup
correctly VLAN configurationi when wrsw_rtud is not running.
The issue is related to the suspected bug #261.
