KVM: x86: Use u64 for address and error code in page fault tracepoint

Browse Source 
Track the address and error code as 64-bit values in the page fault
tracepoint.  When TDP is enabled, the address is a GPA and thus can be a
64-bit value even on 32-bit hosts.  And SVM's #NPF genereates 64-bit
error codes.

Opportunistically clean up the formatting.
