nvmet: fixup crash on NULL device path
When writing an empty string into the device_path attribute the kernel
will crash with
nvmet: failed to open block device (null): (-22)
BUG: unable to handle kernel NULL pointer dereference at 0000000000000000
This patch sanitizes the error handling for invalid device path settings.
Fixes: a07b4970 ("nvmet: add a generic NVMe target")
