[PATCH] spi: spi-topcliff-pch: Remove some dead code

[Christophe JAILLET <christophe.jaillet@wanadoo.fr>]

Since commit 0d35773979b9 ("spi: spi-topcliff-pch: Remove deprecated
create_singlethread_workqueue"), 'retval' is no more used in this function.

So some now dead code can be removed.
Also axe a debug message which looks useless now.
