KVM: Return an "unsigned long", not "u64" for the fixed-1 DR6 bits
Return an "unsigned long" instead of a "u64" from the helper to get the
fixed-1 DR6 bits, as debug registers are natural width registers, not
64-bit registers.
No functional change intended (the fixed-1 bits only set bits in 31:0, and
the sole caller truncates the value to an "unsigned long").
