ecryptfs: initialize new auth_tokens before teardown

ecryptfs_destroy_mount_crypt_stat() checks whether each
auth_tok->global_auth_tok_key is nonzero and if so puts that key.  However,
in some early mount error paths nothing has initialized the pointer, and we
try to key_put() garbage.  Running the bad cipher tests in the testsuite
exposes this, and it's happy with the following change.
