ext4: make sure ex.fe_logical is initialized

The lowest levels of mballoc set all of the fields of struct
ext4_free_extent except for fe_logical, since they are just trying to
find the requested free set of blocks, and the logical block hasn't
been set yet.  This makes some static code checkers sad.  Set it to
various different debug values, which would be useful when
debugging mballoc if these values were to ever show up due to the
parts of mballoc triyng to use ac->ac_b_ex.fe_logical before it is
properly upper layers of mballoc failing to properly set, usually by
ext4_mb_use_best_found().
