ipe: policy_fs: fix kernel-doc warnings

Use the "struct" keyword in kernel-doc when describing struct
ipefs_file. Add kernel-doc for the struct members also.

Don't use kernel-doc notation for 'policy_subdir'. kernel-doc does
not support documentation comments for data definitions.

This eliminates multiple kernel-doc warnings:

security/ipe/policy_fs.c:21: warning: cannot understand function prototype: 'struct ipefs_file '
security/ipe/policy_fs.c:407: warning: cannot understand function prototype: 'const struct ipefs_file policy_subdir[] = '
