bpf: Refactor record_call_access() to extract per-arg logic

Browse source

Extract the per-argument FP-derived pointer handling from
record_call_access() into a new record_arg_access() helper.

The existing loop body — checking arg_is_fp, querying stack access
bytes, and calling record_stack_access/record_imprecise — will be
reused for stack argument slots in the next patch. Factoring it out
now avoids duplicating the logic.

No functional change.
