sdhci-pci: bad error handling in probe function
The goto unmap is too early, we haven't allocated host or done the request_region(). Found by smatch (http://repo.or.cz/w/smatch.git). [ Second error path fix by Pierre Ossman ] Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Pierre Ossman <pierre@ossman.eu>
