HID: wacom: handle kzalloc() allocation failure in wacom_wac_queue_flush()
During wacom_wac_queue_flush() the code calls
kzalloc() to allocate a zero initialised buffer
which it uses as a storage buffer to get data
from the fifo via kfifo_out(). However it does not
check kzalloc() for allocation failure which returns
NULL and could potentially lead to a NULL deref.
Fix this by checking for kzalloc() failure and skipping
the current entry if allocation failure occurs.
