MFC r183211:
Initialize birthtime fields in vn_stat() to prevent stat(2) from
returning uninitialized birthtime. Most file systems don't initialize
birthtime properly in their VOP_GETTATTR().

MFC r183212:
Initialize va_flags and va_filerev properly in VOP_GETATTR(). Don't
initialize va_vaflags and va_spare because they are not part of the
VOP_GETATTR() API. Also don't initialize birthtime to ctime or zero.

MFC rr183213:
Initialize va_rdev to NODEV and va_fsid to VNOVAL before the
VOP_GETATTR() call in vn_stat(). Thus if a file system doesn't
initialize those fields in VOP_GETATTR() they will have a sane default
value.

MFC r183214:
Initialize va_rdev to NODEV instead of 0 or VNOVAL in VOP_GETATTR().
NODEV is more appropriate when va_rdev doesn't have a meaningful value.

MFC r183215:
fdescfs, devfs, mqueuefs, nfs, portalfs, pseudofs, tmpfs and xfs
initialize the vattr structure in VOP_GETATTR() with VATTR_NULL(),
vattr_null() or by zeroing it. Remove these to allow preinitialization
of fields work in vn_stat(). This is needed to get birthtime initialized
correctly.
