Fix projid accounting for xattr objects

Browse Source 
zpool upgraded with 'feature@project_quota' needs re-layout of SA's
to fix the SA_ZPL_PROJID at SA_PROJID_OFFSET (128). Its necessary for
the correct accounting of object usage against its projid.
Old object (created before upgrade) when gets a projid assigned, its
SA gets re-layout via sa_add_projid(). If object has xattr dir, SA
of xattr dir also gets re-layout. But SA re-layout of xattr objects
inside a xattr dir is not done.

Fix zfs_setattr_dir() to re-layout SA's on xattr objects, when setting
projid on old xattr object (created before upgrade).
