target-i386: Remove xlevel & hv-spinlocks option fixups

Browse Source 
The "fixup will be removed in future versions" warnings are
present since QEMU 1.7.0, at least, so users should have fixed
their scripts and configurations, already.

In the case of libvirt users, libvirt doesn't use the "xlevel"
option, and already rejects HyperV spinlock retry count < 0xFFF.

Backports commit c19b85216b5d47d922ac010931d4c7b2d79b2f68 from qemu
