ecryptfs: fix tag 11 packet exact-fit size check

parse_tag_11_packet() rejects a packet when the already-consumed tag and
length bytes plus the packet body exceed the caller supplied maximum
packet size.  The check currently adds one extra byte, even though
*packet_size already includes the tag byte before the length is parsed.

Remove the extra byte so a tag 11 packet that exactly fits the available
buffer is accepted while oversized packets are still rejected.
