1) add local_find_vcpuid_entry to find whether a cpuid leaf exist
in vcpuid cache entries.
2) find_vcpuid_entry will return the found entry if local_find_vcpuid_entry
return is not null. Otherwise, call local_find_vcpuid_entry again
when necessary.
In this case, there could eliminate recursion in find_vcpuid_entry.

Fixed three MISRA-C violations:
11S: No brackets to loop body
7C: Procedure has more than one exit point.
8D: DD data flow anomalies found.
initialize read_map and write_map in the declaration statements.
Fixed one bug:
Use "msr <= 0x1FFFU" instead of "msr < 0x1FFFU" because 0x1FFF is a valid MSR
bitmap address.

vmx.c should only take care host vmx operations, which should not
contain vcpu reference, so refine vmx on/off APIs, move out use
of vcpu by adding one per cpu vmcs_run pointer.
as now each pcpu only run on one vcpu, so just keep running vmcs
in per cpu vmcs_run pointer is enough.
