+[SCSI] fusion: remove VMWare guest OS remounted as read only work around
+
+This address the issue of VMWare guest OS being remounted as read-only
+becuase the underlying device was held busy too long and at the
+same time address Engenio MPP driver concerns over infinite retries.
+This patch removes the code that snoops the SAM STATUS on busy, which
+would be returning DID_BUS_BUSY, instead we return the status as is.
+Retry hanlding seems to be properly handled in scsi_softirq_done,
+where a busy sam status would only occurr for the time specified by
+(cmd->allowed +1) * cmd->timeout_per_command.
