[PATCH v2] staging: media: atomisp: prefer kcalloc over kzalloc with multiply

[Andrew Soto]

Optimize memory allocation layout in sh_css_params.c by replacing
the raw multiplication inside kzalloc() with a type-safe kcalloc()
array allocation wrapper.

This prevents potential integer overflow vulnerabilities by validating
the array size calculations before interacting
with the kernel heap allocator, aligning the driver with modern kernel
memory allocation standards.
