scsi: libsas: Delete sas_ha_struct.lldd_module

Since libsas was introduced in commit 2908d778 ("[SCSI] aic94xx: new
driver"), sas_ha_struct.lldd_module has only ever been set, so remove it.

Struct scsi_host_template already has a reference to the LLD driver
module as to stop the driver being removed unexpectedly.
