drm/gma500: Fix possible out of bounds read

commit 7ccca1d upstream.

Fix possible out of bounds read, by adding missing comma.
The code may read pass the end of the dsi_errors array
when the most significant bit (bit raspberrypi#31) in the intr_stat register
is set.
This bug has been detected using CppCheck (static analysis tool).
