[SCSI] fix compile error on module_refcount

  LD      .tmp_vmlinux1
drivers/built-in.o(.text+0x8e1f9): In function `scsi_device_put':
drivers/scsi/scsi.c:887: undefined reference to `module_refcount'
make: *** [.tmp_vmlinux1] Error 1

There are only two users of module_refcount() outside of kernel/module.c
and the other one uses ifdef's similar to this.
