drm/msm/dpu: make error messages at dpu_core_irq_register_callback() more sensible

Browse Source 
commit 8844f467d6 upstream.

There is little point in using %ps to print a value known to be NULL. On
the other hand it makes sense to print the callback symbol in the
'invalid IRQ' message. Correct those two error messages to make more
sense.
