pidfs: use anon_inode_getattr()

Browse Source 
So far pidfs did use it's own version. Just use the generic version. We
use our own wrappers because we're going to be implementing our own
retrieval properties soon.

* User space expects pidfs inodes to have no file type in st_mode.

* In particular, 'lsof' has this legacy logic:
*
* type = s->st_mode & S_IFMT;

* ...
* case 0:
* if (!strcmp(p, "anon_inode"))
* Lf->ntype = Ntype = N_ANON_INODE;
*
* to detect our old anon_inode logic.
*
* Rather than mess with our internal sane inode data, just fix it
* up here in getattr() by masking off the format bits.
