[PATCH v2] spi/spi: don't release the spi device twice

[Sebastian Andrzej Siewior <bigeasy-hfZtesqFncYOwBW4kG4KsQ@public.gmane.org>]

This was fixed by David Lamparter in v2.6.36-rc5 3486008
("spi: free children in spi_unregister_master, not siblings") and broken
again in v2.6.37-rc1~2^2~4 during the merge of 2b9603a0 ("spi: enable
spi_board_info to be registered after spi_master").
