scsi: hisi_sas: Directly return when running I_T_nexus reset if phy disabled

Browse source

At hisi_sas_debug_I_T_nexus_reset(), we call sas_phy_reset() to reset a
phy. But if the phy is disabled, sas_phy_reset() will directly return
-ENODEV without issue a phy reset request.

If so, We can directly return -ENODEV to libsas before issue a phy
reset.
