This patch removes the following warnings and related ones.
Plus some cosmetics.

Account for number of online cpus and use that in loops iterating over
the list of vpus instead of scanning the full array unconditionally.
This patch is a building block to facilitate allowing to bump up
the size of MAX_VCPUS significantly.

Remove some unnecessary blank lines to accord with Kernel's coding style.
Also remove vcpu_get_itir_on_fault due to no reference to it.

1. Increase the size of data area to 64M
2. Support more vcpus and memory, 128 vcpus and 256G memory are supported
for guests.
3. Add the boundary check for memory and vcpu allocation.
With this patch, kvm guest's data area looks as follow:
*
* +----------------------+ ------- KVM_VM_DATA_SIZE
* | vcpu[n]'s data | | ___________________KVM_STK_OFFSET
* | | | / |
* | .......... | | /vcpu's struct&stack |
* | .......... | | /---------------------|---- 0
* | vcpu[5]'s data | | / vpd |
* | vcpu[4]'s data | |/-----------------------|
* | vcpu[3]'s data | / vtlb |
* | vcpu[2]'s data | /|------------------------|
* | vcpu[1]'s data |/ | vhpt |
* | vcpu[0]'s data |____________________________|
* +----------------------+ |
* | memory dirty log | |
* +----------------------+ |
* | vm's data struct | |
* +----------------------+ |
* | | |
* | | |
* | | |
* | | |
* | | |
* | | |
* | | |
* | vm's p2m table | |
* | | |
* | | |
* | | | |
* vm's data->| | | |
* +----------------------+ ------- 0
* To support large memory, needs to increase the size of p2m.
* To support more vcpus, needs to ensure it has enough space to
* hold vcpus' data.
