Many BPF_MAP_CREATE validation failures currently return -EINVAL without any explanation to userspace. Plumb common syscall log attributes into map_create(), create a verifier log from bpf_common_attr::log_buf/log_size/log_level, and report map-creation failure reasons through that buffer. This improves debuggability by allowing userspace to inspect why map creation failed and read back log_true_size from common attributes.
