Scalable endpoint fails with -22 on GNI

[bcernohous]

Verify proper functioning of scalable EP usage

I ran the attached fi_write_scalable_ep.c

fi_write_scalable_ep.zip

The sockets provider appears to be working.

But gni fails with fi_scalable_ep_bind ret:-22 error: Invalid argument

$ cc -g -o fi_write_scalable_ep fi_write_scalable_ep.c -I/.../libfabric-test/builds/latest-libfabric.../include/ -L/.../libfabric-test/builds/latest-libfabric.../lib/ -lfabric

and the trace is

The GNI provider binding method for sep's isn't correct for address vectors. It assumes the rx/tx contexts are already allocated prior to binding the sep to an av. Should have a fix on Monday.

I have a fix for this but I assume the test is still pretty buggy. I notice it frees hints then proceeds on further in the program to do a strcmp with a field in hints. @bcernohous
