Tal Lossos f7c3d7615e bpf: Change inode_storage's lookup_elem return value from NULL to -EBADF
[ Upstream commit 769c18b254ca191b45047e1fcb3b2ce56fada0b6 ]

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.
