msc_a,vlr: add is_ciphering_required (accurately named)
For establishing Layer 3, pass a flag from msc_a to VLR that indicates
to fail if encryption is not possible.
An earlier patch [1] renamed a previously existing flag
require_ciphering to is_ciphering_to_be_attempted, because the naming
was not accurate. This new flag now indicates what its name suggests.
This new flag is needed for upcoming patch [2] to distinguish between
optional and mandatory encryption.
