The current default value for hv-spinlocks is 0xFFFFFFFF (meaning
"never retry").  However, the value is stored as a signed
integer, making the getter of the hv-spinlocks QOM property
return -1 instead of 0xFFFFFFFF.

Fix this by changing the type of X86CPU::hyperv_spinlock_attempts
to uint32_t.  This has no visible effect to guest operating
systems, affecting just the behavior of the QOM getter.
