scsi: hisi_sas: Use abort task set to reset SAS disks when discovered 

mainline inclusion
from mainline-v6.2-rc4
commit 037b4805
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I6NPLN
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=037b48057e8b485a8d72f808122796aeadbbee32



----------------------------------------------------------------------

Currently clear task set is used to abort all commands remaining in the
disk when the SAS disk is discovered, and if the disk is discovered by two
initiators, other I_T nexuses are also affected. So use abort task set
instead and take effect only on the specified I_T nexus.
