scsi: hisi_sas: Add slave_destroy interface for v3 hw
driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7BNF8 CVE: NA ---------------------------------------------------------------------- A WARNING is triggered when executing link reset of remote PHY and rmmod SAS driver simultaneously. Following is the WARNING log: WARNING: CPU: 61 PID: 21818 at drivers/base/core.c:1347 __device_links_no_driver+0xb4/0xc0 Call trace: __device_links_no_driver+0xb4/0xc0 device_links_driver_cleanup+0xb0/0xfc __device_release_driver+0x198/0x23c device_release_driver+0x38/0x50 bus_remove_device+0x130/0x140 device_del+0x184/0x434 __scsi_remove_device+0x118/0x150 scsi_remove_target+0x1bc/0x240 sas_rphy_remove+0x90/0x94 sas_rphy_delete+0x24/0x3c sas_destruct_devices+0x64/0xa0 [libsas] sas_revalidate_domain+0xe4/0x150 [libsas] process_one_work+0x1e0/0x46c worker_thread+0x15c/0x464 kthread+0x160/0x170 ret_from_fork+0x10/0x20 ---[ end trace 71e059eb58f85d4a ]--- During SAS phy up, link->status is set to DL_STATE_AVAILABLE in device_links_driver_bound, then this setting influences __device_links_no_driver() before driver rmmod and caused WARNING. So we add the slave_destroy interface, to make sure link is removed after flush workque.
