bpf: Remove unused backtrack_state helper functions
The function are defined in the verifier.c file, but not called
elsewhere, so delete the unused function.

kernel/bpf/verifier.c:3453:20: warning: unused function 'bt_clear_slot'
kernel/bpf/verifier.c:3488:20: warning: unused function 'bt_is_slot_set'
