Willy Tarreau f26c6f9404 tcp: drop the hash_32() part from the index calculation ...

[ Upstream commit e8161345dd ]

In commit 190cc82489 ("tcp: change source port randomizarion at
connect() time"), the table_perturb[] array was introduced and an
index was taken from the port_offset via hash_32(). But it turns
out that hash_32() performs a multiplication while the input here
comes from the output of SipHash in secure_seq, that is well
distributed enough to avoid the need for yet another hash.
