On module load, creates a debugfs parent 'rssd' in debugfs root. Then for each
device, create a new node with corresponding disk name. Under the new node, two
entries 'registers' and 'flags' are created.

NOTE: These entries were removed from sysfs in the previous patch

* If a ncq  command time out and a non-ncq command is active, skip restart port
* Queue(pause) ncq commands during operations spanning more than one non-ncq commands - secure erase, download microcode
* When a non-ncq command is active, allow incoming non-ncq commands to wait instead of failing back
* Changed timeout for download microcode and smart commands
* If the device in write protect mode, fail all writes (do not send to device)
* Set maximum retries to 2

thread takes the responsibility of rebuild monitoring, and probe returns good
status.
