bpf: Remove dynptr check in check_stack_range_initialized()
For a MEM_UNINIT ("raw mode") helper argument,
check_stack_range_initialized() open-coded a scan that rejected any
STACK_DYNPTR slot in the range with "potential write to dynptr". This
duplicated, and was stricter than, the handling that runs when the
buffer is actually marked initialized. check_helper_call() later replays
the write byte by byte via check_mem_access(), which goes through
destroy_if_dynptr_stack_slot(), which rejects overwritting a referenced
dynptr. Therefore drop the redundant scan and rely on check_mem_access().
