bpf: opcodes: fix regression in BPF disassembler
This patch fixes a regression recently introduced in the BPF disassembler, that was assuming an abfd was always available in info->section->owner. Apparently this is not so in GDB, and therefore https://sourceware.org/bugzilla/show_bug.cgi?id=30705. Tested in bpf-unkonwn-none. opcodes/ChangeLog: 2023-07-31 Jose E. Marchesi <jose.marchesi@oracle.com> PR 30705 * bpf-dis.c (print_insn_bpf): Check that info->section->owner is actually available before using it.
