scsi: hisi_sas: fix free'ing in probe and remove

Browse source

This patch addresses 4 problems in the module probe/remove:

 - When hisi_sas_shost_alloc() fails after we alloc shost memory, we
   should free shost memory before the function returns.

 - When hisi_sas_probe() fails after we alloc the HBA memories, we
   should also free the HBA memories.

 - We should free shost memory at the end of hisi_sas_remove().

 - sha->core.shost is set twice, so remove extra set.
