RDMA: Check for NULL mode in .devnode methods
Commits 71c29bd5c235 ("IB/uverbs: Add devnode method to set path/mode")
and c3af0980ce01 ("IB: Add devnode methods to cm_class and umad_class")
added devnode methods that set the mode.
However, these methods don't check for a NULL mode, and so we get a
crash when unloading modules because devtmpfs_delete_node() calls
device_get_devnode() with mode == NULL.
Add the missing checks.
