Ping Cheng 003280bd88 HID: wacom: Fix memory leakage caused by kfifo_alloc 
commit 37309f47e2 upstream.

As reported by syzbot below, kfifo_alloc'd memory would not be freed
if a non-zero return value is triggered in wacom_probe. This patch
creates and uses devm_kfifo_alloc to allocate and free itself.

BUG: memory leak
unreferenced object 0xffff88810dc44a00 (size 512):
