Wenwen Wang f3ee3badcb ecryptfs: fix a memory leak bug in parse_tag_1_packet()

commit fe2e082f5d upstream.

In parse_tag_1_packet(), if tag 1 packet contains a key larger than
ECRYPTFS_MAX_ENCRYPTED_KEY_BYTES, no cleanup is executed, leading to a
memory leak on the allocated 'auth_tok_list_item'. To fix this issue, go to
the label 'out_free' to perform the cleanup work.
