kdbus: connection: fix handling of failed fget()
The patch 5fc8dd5c84fc: "kdbus: add connection, queue handling and
message validation code" from Sep 11, 2014, leads to the following
static checker warning:
ipc/kdbus/connection.c:2000 kdbus_cmd_send()
warn: 'cancel_fd' isn't an ERR_PTR
Fix this by checking for NULL pointers returned from fget().
