There is no reason to treat VM_SEALED in a special way, in each other case
in which a VMA flag is unavailable due to configuration, we simply assign
that flag to VM_NONE, so make VM_SEALED consistent with all other VMA
flags in this respect.
Additionally, use the next available bit for VM_SEALED, 42, rather than
arbitrarily putting it at 63 and update the declaration to match all other
VMA flags.
No functional change intended.
