libertas_spi: Use workqueue in hw_host_to_card
Use workqueue to perform SPI xfers, it's necessary to fix
nasty "BUG: scheduling while atomic", because
spu_write() calls spi_sync() and spi_sync() may sleep, but
hw_host_to_card() callback can be called from atomic context.
Remove kthread completely, workqueue now does its job.
Restore intermediate buffers which were removed in commit
86c34fe89e9cad9e1ba4d1a8bbf98259035f4caf that introduced
mentioned bug.
