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.

Fixes: 7b3ad5abf027 ("staging: Import the BCM2835 MMAL-based V4L2 camera driver.")
