[PATCH openEuler-1.0-LTS] RDMA/srp: Do not call scsi_done() from srp_abort()

From: Bart Van Assche <bvanassche(a)acm.org> stable inclusion from stable-v5.10.199 commit 26788a5b48d9d5cd3283d777d238631c8cd7495a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I95B1O CVE: CVE-2023-52515 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit e193b7955dfad68035b983a0011f4ef3590c85eb ] After scmd_eh_abort_handler() has called the SCSI LLD eh_abort_handler callback, it performs one of the following actions: * Call scsi_queue_insert(). * Call scsi_finish_command(). * Call scsi_eh_scmd_add(). Hence, SCSI abort handlers must not call scsi_done(). Otherwise all the above actions would trigger a use-after-free. Hence remove the scsi_done() call from srp_abort(). Keep the srp_free_req() call before returning SUCCESS because we may not see the command again if SUCCESS is returned.
