Tal Lossos 769c18b254 bpf: Change inode_storage's lookup_elem return value from NULL to -EBADF ... bpf_fd_inode_storage_lookup_elem() returned NULL when getting a bad FD, which caused -ENOENT in bpf_map_copy_value. -EBADF error is better than -ENOENT for a bad FD behaviour. The patch was partially contributed by CyberArk Software, Inc.
