Subject: [PATCH] ibacm: acm.c load plugin while it is soft link

NOTE: THIS ONE IS RHEL SPECIFIC WORKAROUND COMMIT.
https://github.com/linux-rdma/rdma-core/pull/923

Because of commit ad5d934d688911149d795aee1d3b9fa06bf171a9,
the provider libdsap.so.1.0.0 was not opened/used for address resolution
for OPA device.

As discussed in this closed PR:
https://github.com/linux-rdma/rdma-core/pull/848

I create a soft link for libdsap.so => libdsap.so.1.0.0 . The soft link
was ignored because it is a not regular file.
