mlx4_core: Fix thinko in QP destroy (incorrect bitmap_free)
Fix thinko in commit eaf559bf ("mlx4_core: Don't free special QPs in QP number bitmap"). The old commit had the logic exactly backwards and ended up freeing *only* special QPs, which not only left the original bug in place but also introduced the problem that the QP number bitmap would get full after a while. Found by Dotan Barak of Mellanox. Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
