[ofa-general] [PATCH][master] dapl: cma provider needs to support lower inline send default for iWARP

[Arlin Davis]

IB and iWARP work best with different defaults. Add transport check
and set default accordingly. 64 for iWARP, 200 for IB.

DAPL_MAX_INLINE environment variable is still used to override.
