BUG/MAJOR: sessions: unlink session from list on out of memory

Since embryonic sessions were introduced in 1.5-dev12 with commit
2542b53 ("MAJOR: session: introduce embryonic sessions"), a major
bug remained present. If haproxy cannot allocate memory during
session_complete() (for example, no more buffers), it will not
unlink the new session from the sessions list. This will cause
memory corruptions if the memory area from the session is reused
for anything else, and may also cause bogus output on "show sess"
on the CLI.

This fix must be backported to 1.5.
