eCryptfs: initialize payload_len in keystore.c
This is meant to remove a compiler warning. It should not make any
functional change.
payload_len should be initialized when it is passed to
write_tag_64_packet() as a pointer. If that call fails, this function
should return early, and payload_len won't be used.
