If\nthe CREATE succeeds but a later command returns an error, the function\nmust retain the CREATE FID so common cleanup can issue SMB2_close(). It\nalso must not treat a response error as a valid CREATE.\n\nValidate the CREATE response before using its fields, record the FIDs, and\nmark the handle open before handling errors from later compound commands.\nMove the -EREMCHG reconnect handling before response validation so a\nmissing response does not hide the reconnect request. Count the handle\nwhen it is marked open; confirmed close responses decrement the counter,\nwhile existing close retry behavior remains best effort on transport\nfailures."
