xfs_iformat_fork is a weird catchall. Split it into one helper for the data fork and one for the attr fork, and then call both helper as well as the COW fork initialization from xfs_inode_from_disk. Order the COW fork initialization after the attr fork initialization given that it can't fail to simplify the error handling. Note that the newly split helpers are moved down the file in xfs_inode_fork.c to avoid the need for forward declarations.

Remove the XFS wrappers for converting from and to the kuid/kgid types. Mostly this means switching to VFS i_{u,g}id_{read,write} helpers, but in a few spots the calls to the conversion functions is open coded. To match the use of sb->s_user_ns in the helpers and other file systems, sb->s_user_ns is also used in the quota code. The ACL code already does the conversion in a grotty layering violation in the VFS xattr code, so it keeps using init_user_ns for the identity mapping.

When inodes are freed in xfs_ifree(), di_flags is cleared (so extent size hints are removed) but the actual extent size fields are left intact. This causes the extent hint validators to fail on freed inodes which once had extent size hints.

When the inode is in extent format, it can't have more extents that fit in the inode fork. We don't currenty check this, and so this corruption goes unnoticed by the inode verifiers. This can lead to crashes operating on invalid in-memory structures. Attempts to access such a inode will now error out in the verifier rather than allowing modification operations to proceed.

In xfs_imap_to_bp(), we convert a -EFSCORRUPTED error to -EINVAL if we are doing an untrusted lookup. This is done because we need failed filehandle lookups to report -ESTALE to the caller, and it does this by converting -EINVAL and -ENOENT errors to -ESTALE. The squashing of EFSCORRUPTED in imap_to_bp makes it impossible for for xfs_iget(UNTRUSTED) callers to determine the difference between "inode does not exist" and "corruption detected during lookup". We realy need that distinction in places calling xfS_iget(UNTRUSTED), so move the filehandle error case handling all the way out to xfs_nfs_get_inode() where it is needed.
