gpu: nvgpu: add pid field to gk20a_event_id_data

QNX is going to reuse the 'struct gk20a_event_id_data' data structure
for its event handling. Contrary to linux which works on fd polling,
QNX needs the information about the pid to find out which process to
deliver the event to.

The patch adds the requisite field.
