[PATCH] bpf: Fix unsigned 'datasec_id' compared with zero in check_pseudo_btf_id

From: Kaixu Xia The unsigned variable datasec_id is assigned a return value from the call to check_pseudo_btf_id(), which may return negative error code. Fixes coccicheck warning: ./kernel/bpf/verifier.c:9616:5-15: WARNING: Unsigned expression compared with zero: datasec_id > 0 Reported-by: T
