Dejan Mircevski 46b4b59945 cql3: Fix value_for when restriction is impossible 
Previously, single_column_restrictions::value_for() assumed that a
column's restriction specifies exactly one value for the column.  But
since 37ebe521e3, multiple equalities on the same column are allowed,
so the restriction could be a conjunction of conflicting
equalities (eg, c=1 AND c=0).  That violates an assert and crashes
Scylla.

This patch fixes value_for() by gracefully handling the
impossible-restriction case.

Fixes #7772
