Kumar Kartikeya Dwivedi 7ada3787e9 bpf: Check for NULL return from bpf_get_btf_vmlinux
When CONFIG_DEBUG_INFO_BTF is disabled, bpf_get_btf_vmlinux can return a
NULL pointer. Check for it in btf_get_module_btf to prevent a NULL pointer
dereference.

While kernel test robot only complained about this specific case, let's
also check for NULL in other call sites of bpf_get_btf_vmlinux.

Fixes: 9492450fd2 ("bpf: Always raise reference in btf_get_module_btf")
