HID: logitech: check the return value of create_singlethread_workqueue

[ Upstream commit 6c44b15e1c9076d925d5236ddadf1318b0a25ce2 ]

create_singlethread_workqueue may fail and return NULL. The fix checks if it is
NULL to avoid NULL pointer dereference.  Also, the fix moves the call of
create_singlethread_workqueue earlier to avoid resource-release issues.
