[LU-6816] libzfs_load_module() not exported in future ZFS release

Description

zfs_init() currently calls libzfs_load_module(), which is no longer externally visible in ZFS master.

The intent of the call to libzfs_load_module apparently is to make zfs_init() fail silently if libzfs is not installed, but fail with an error message if libzfs is installed but initialization fails. However it's not clear how this could ever work.

In addition, I believe this could be better addressed by not reporting errors during probing, but instead reporting them only after osd_is_lustre() fails.

A patch will be submitted to remove the invalid call, and a separate ticket for the revamp of the osd initialization error handling.
