[PATCH 2/7] cpu_x86.c: remove 'guest' param from x86Compute()

[Daniel Henrique Barboza <danielhb413@xxxxxxxxx>]

x86Compute() is a static function called only by virCPUx86Compare()
which passes NULL to the 'guest' parameter of x86Compute().

The last caller of x86Compute() that used it with 'guest' != NULL
was an API called 'cpuGuestData'. This API was dropped by commit
03fa904c0c0cb2 a few years ago. Since then all callers of x86Compute()
uses it with 'guest' = NULL.

Removing the 'guest' parameter allow us to remove a good chunk of
logic that isn't being used for awhile.
