mlx4_core: mtts resources units changed to offset
In the previous implementation mtts are managed by:
1. order - log(mtt segments), 'mtt segment' groups several mtts together.
2. first_seg - segment location relative to mtt table.
In the current implementation:
1. order - log(mtts) rather than segments
2. offset - mtt index in mtt table
Note: The actual mtt allocation is made in segments but it is
transparent to callers.
Rational: The mtt resource holders are not interested on how the allocation
of mtt is done, but rather on how they will use it.
