[SCSI] mpt2sas: when Async scanning is enabled then while scanning, devices are removed but their transport layer entries are not removed
When Async scanning mode is enabled and device scanning is in progress then devices should not be removed. But in actuality, devices are removed but their transport layer entries are not removed. This causes error to add the same device to the transport layer after host reset or diagnostic reset. So, in this patch, modified the code in such a way that device is not removed when Async scanning mode is enabled and device scanning is in progress.
