bpf: Fix unsigned 'datasec_id' compared with zero in check_pseudo_btf_id
The unsigned variable datasec_id is assigned a return value from the call
to check_pseudo_btf_id(), which may return negative error code.
This fixes the following coccicheck warning:
./kernel/bpf/verifier.c:9616:5-15: WARNING: Unsigned expression compared with zero: datasec_id > 0
Fixes: eaa6bcb71ef6 ("bpf: Introduce bpf_per_cpu_ptr()")
