When a system runs out of memory and the function
ptlrpc_register_bulk() is called from ptl_send_rpc() the call to
LNetMEAttach() fails due to failure to allocate memory.  This forces
the code into an error path, which most probably previously went
untested.  The error path:
if (rc != 0) {
        CERROR("%s: LNetMEAttach failed x"LPU64"/%d: rc = %dn",
                desc->bd_export->exp_obd->obd_name, xid,
                posted_md, rc);
        break;
}
This print assumes that desc->bd_export is not NULL.  However, it is.
In fact it is expected to be NULL.  desc->bd_import is the correct
structure to access in this case.

ll_lookup_it() checks for O_CREAT in struct lookup_intent's
it_create_mode member which is nonsensical, as it_create_mode is used
for file mode bits (S_IFREG, S_IRUSR, ...). Fix this by just checking
for IT_CREATE in it_op. This will not affect the behavior of either
function, since if O_CREATE (0100) is actually set in o_create_mode
then IT_CREATE must have been set in it_op. In ll_atomic_open() check
for O_CREAT in the open_flags parameter rather than testing mode.
