bpf: Mark dentry->d_inode as trusted_or_null
LSM hooks such as security_path_mknod() and security_inode_rename() have
access to newly allocated negative dentry, which has NULL d_inode.
Therefore, it is necessary to do the NULL pointer check for d_inode.
Also add selftests that checks the verifier enforces the NULL pointer
check.
