Jiasheng Jiang b1712a691b HID: potential dereference of null pointer
commit 13251ce1dd9bb525da2becb9b26fdfb94ca58659 upstream.

The return value of devm_kzalloc() needs to be checked.
To avoid hdev->dev->driver_data to be null in case of the failure of
alloc.

Fixes: 14c9c014babe ("HID: add vivaldi HID driver")
