scsi: hisi_sas: Reset PHY again if phyup timeout

Browse source

In commit 89954f024c ("scsi: hisi_sas: Ensure all enabled PHYs up
during controller reset"), we enable PHYs in parallel through async
operations and wait for PHYs come up. However, for some directly
attached SATA disks, the PHY not come up after a timeout period and the
hardware is not ready.  At this time, we should get the latest PHY
hardware state, if the new PHY state is not ready but the old PHY state
is ready, call work HISI_PHYE_LINK_RESET to give it another chance to
phyup.
