KVM: x86: Use <linux/lockdep.h> for lockdep header inclusion

When KVM added a lockdep assertion to catch unexpected cases where guest
CPUID lookups are performed in IRQ disabled context, it used
"linux/lockdep.h" for header inclusion even though lockdep.h is a
kernel wide header.  Switch to using <linux/lockdep.h>.
