As 'zero' can be a perfectly good id, it can be picked up as
a NULL from userspace, avoid issues in API and user apps if stream
handle is zero.

Send stream ids to the user instead of handles, then when
the id is coming from user dspbridge can retrive the handle
using id and avoid using invalid handles.

Use idr kernel library to send/receive node ids to the
user instead of kernel address.
This id will be use to access the node handles at the
kernel side, if id does not match to any handle
error -EFAULT is returned.

When dsp_notifications array is received from user,
dspbridge verifies the array has valid pointers
and dsp_notification structures. However, these
structures contain pointers that need to be
checked for valid handles.
