GPUCORE-36665 Fix OOB issue on KBASE_IOCTL_CS_TILER_HEAP_INIT

'group_id' member of the ioctl (KBASE_IOCTL_CS_TILER_HEAP_INIT) struct
must be validated before initializing CSF tiler heap.
Otherwise out-of-boundary of memory group pools array for the CSF tiler
heap could happen and will potentially lead to kernel panic.
