The second argument of sops->show_options() was changed from a 'struct vfsmount *' to a 'struct dentry *'. Add an autoconf check to detect the API change and then conditionally define the expected interface. In either case we are only interested in the zfs_sb_t. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #549
