zfs -V: Print userland version even if kernel module not loaded

Browse Source 
Running zfs -V when the modules are not loaded would currently 
result in the following output:

    zfs_version_kernel() failed: No such file or directory

Note the lack of userland version output.  Reorder the code to
ensure the userland version is printed even when the kmods
are not loaded.
