  1. prov/efa: Use shm with 1.19 API 

    The hmem_data field in ofi_mr will be ignored for api
version < 1.19. In order to make shm use the gdrcopy
handle stored in the hmem_data field, we need to call
shm's fi_getinfo with 1.19 version.

  2. prov/efa: Remove the version check in efa_mr.c 

    Efa is using the hmem_data internally to pass
gdrcopy handle to shm, so it should not care
what api version the application was using.
Since this code is already part of libfabric
1.19, there is no need to add a version check.
