scsi: libsas: Delete sas_ssp_task.retry_count

Browse source 
Since libsas was introduced in commit 2908d778ab ("[SCSI] aic94xx: new
driver"), sas_ssp_task.retry_count is only ever set, so delete it.

The aic94xx driver also had its own retry_count definition in struct scb
sub-structs, which may have caused a mix-up.
