Patch for red-storm.

Description:
A temporary patch for redstorm, must open a file in the same parallel
data filesystem before H5_init_library.  Otherwise, it hangs with error:
(client.c:568:ptlrpc_check_status()) @@@ type == PTL_RPC_MSG_ERR, err == -114 req@0x57a9660 x1/t0 o38->mds_l2@MDS_PEER_UUID:12 lens 240/272 ref 1 fl Rpc:R/100000/0 rc 0/-114

Platforms tested:
Red-storm.
