scsi: hisi_sas: Use sas_ata_wait_after_reset() in IT nexus reset

We have seen errors like this when a SATA device is probed:

[524.566298] hisi_sas_v3_hw 0000L74:02.0: erroneous completion iptt=4096 ...
[524.582827] sas: TMF task open reject failed 500e004aaaaaaaa00

Since commit 21c7e972 ("scsi: hisi_sas: Disable SATA disk phy for
severe I_T nexus reset failure"), we issue an ATA softreset to disks after
a phy reset to ensure that they are in sound working order. If the
softreset is issued before the remote phy has come back up then the
softreset will fail (errors as above). Remedy this by waiting for the phy
to come back up after the reset.
