[PATCH] pipeline: rpi: pisp: Fix uninitialized variable warning

[Laurent Pinchart]

gcc 13.3.0 from buildroot 2024.11.1 complains about an uninitialized
variable. This is a false positive as the cfe_ array can't be empty.
Nonetheless, it breaks builds, so initialize the variable to work around
the issue.
