[PATCH] media: staging/intel-ipu3: css: simplify expression

[Deepak R Varma <mh12gx2825@gmail.com>]

An array index computed inside square brackets leading to complexity
and code line exceeding 80 character. Add new variable to compute
array index separately and use it as an index during assignment.
