[PATCH rdma-core V1] Remove unused HIDDEN gcc attribute

[PATCH rdma-core V1] Remove unused HIDDEN gcc attribute

[Leon Romanovsky]

The attribute HIDDEN was declared in almost every provider, but it wasn't
used, except in libibverbs. This attribute is configured by linker map
now and can be safely removed.
