scsi: hisi_sas: Call I_T_nexus after soft reset for SATA disk

In commit 21c7e97 ("scsi: hisi_sas: Disable SATA disk phy for severe
I_T nexus reset failure"), if the softreset fails upon certain
conditions, the PHY connected to the disk is disabled directly. Manual
recovery is required, which is inconvenient for users in actual use.

In addition, SATA disks do not support simultaneous connection of multiple
hosts. Therefore, when multiple controllers are connected to a SATA disk
at the same time, the controller which is connected later failed to issue
an ATA softreset to the SATA disk. As a result, the PHY associated with
the disk is disabled and cannot be automatically recovered.

Now that, we will not focus on the execution result of softreset. No
matter whether the execution is successful or not, we will directly carry
out I_T_nexus_reset.
