Ensure an error message is logged when the 'zfs.sh' script fails to either load a module or if udev fails to create the /dev/zfs device. Error messages for missing KERNEL_MODULES are suppressed because that functionality may just be built-in to the kernel. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov>
