iflib: Prevent watchdog from resetting idle queues

While changing link state in iflib_link_state_change(), queues are
marked as IFLIB_QUEUE_IDLE to disable watchdog. Currently, iflib_timer()
watchdog does not check for previous queue status before marking it as
IFLIB_QUEUE_HUNG.

This patch adds check of queue status before marking it as hung.
