All unimplemented VFS ops now have entries in kern/vfs_default.c that return

reasonable defaults.

This avoids confusing and ugly casting to eopnotsupp or making dummy functions.
Bogus casting of filesystem sysctls to eopnotsupp() have been removed.

This should make *_vfsops.c more readable and reduce bloat.
