LU-3617 o2ib: Correctly detect infiniband features

The header file rdma_cm.h refers to the fc_compat.h
header for a function declaration. Lustre test to
see if certain infiniband features are available but
in order for those test to work properly the
fc_compact.h header must be included. Otherwise the
test will always fail thus disabling potential
features. This patch includes fc_compact.h when needed.
