scsi: target: use scoped_with_init_fs() for APTPL metadata
Use scoped_with_init_fs() to temporarily override current->fs for
the filp_open() call in __core_scsi3_write_aptpl_to_file() so the
path lookup happens in init's filesystem context.
__core_scsi3_write_aptpl_to_file() ← core_scsi3_update_and_write_aptpl()
← PR command handlers ← target_queued_submit_work() ← kworker
