Set devp even if probing fails.
Without the patch the following problem occurs: If the first block device is not probed successfully no block device is passed by bootefi to the EFI executable.
The problem was reported by Andreas Färber in https://lists.denx.de/pipermail/u-boot/2017-April/287432.html
For testing I used an odroid-c2 with a dts including &sd_emmc_a { status = "okay"; } This device does not exist on the board and cannot be initialized.
