Luis Henriques (SUSE) 3236afd1a2 ext4: fix possible tid_t sequence overflows ...

[ Upstream commit 63469662cc45d41705f14b4648481d5d29cf5999 ]

In the fast commit code there are a few places where tid_t variables are
being compared without taking into account the fact that these sequence
numbers may wrap.  Fix this issue by using the helper functions tid_gt()
and tid_geq().
