Subject: [PATCH] dax: quiet bdev_dax_supported()
Git-commit: 66a86cc10945648cf506ef314b98deeb7af06419
Patch-mainline: v4.15-rc1
References: bsc#1104888

Before we add another failure reason, quiet the existing log messages.
Leave it to the caller to decide if bdev_dax_supported() failures are
errors worth emitting to the log.
