LP:782269 - xt_xn_init_db() locks are initialized twice, leaking resources

The loop below is run twice in xt_xn_init_db() . It initialized the same pthread_cond structures each time. It leaks events on Windows (since each pthread_cond contains 3 events that would be created with CreateEvent)

Moreover, it creates problems (i.e debug exceptions) when mysqld is run under application verifier.

Problematic code :

for (u_int i=0; i<XT_XN_NO_OF_SEGMENTS; i++)

{ seg = &db->db_xn_idx[i]; XT_XACT_INIT_LOCK(self, &seg->xs_tab_lock); ... }
