spi: Return deferred probe error when controller isn't yet available

Browse Source 
[ Upstream commit 9c22ec4ac27bcc5a54dd406da168f403327a5b55 ]

If the controller is not available, it might be in the future and
we would like to re-probe the peripheral again. For that purpose
return deferred probe.
