CVE-2023-52515 RDMA/srp: Do not call scsi_done() from srp_abort()

In the Linux kernel, the following vulnerability has been resolved:

RDMA/srp: Do not call scsi_done() from srp_abort()

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.
