scsi: hisi_sas: Use libsas internal abort support 

Use the common libsas internal abort functionality.

In addition, this driver has special handling for internal abort timeouts -
specifically whether to reset the controller in that instance, so extend
the API for that.

Timeout is now increased to 20 * Hz from 6 * Hz.

We also retry for failure now, but this should not make a difference.
