Subject: staging: vc04_services: fix information leak in create_component()

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

commit f37e76abd614b68987abc8e5c22d986013349771 upstream.

The m.u.component_create.pid field is for debugging and in the mainline
kernel it's not used anything.  However, it still needs to be set to
something to prevent disclosing uninitialized stack data.  Set it to
zero.
