[PATCH] cpu: Remove pointless check
These two pointers can never be NULL since they are initialised to a reference
of a struct. This became apparent when commit 210a19539447 added a VIR_DEBUG
which used both pointers because due to the concise condition the compiler saw
that if the "and" part of the condition did short-circuit (and it assumed that
can happen) the second variable would not be initialised, but it is used in the
debugging message, so the build failed with:
In file included from ../src/cpu/cpu_x86.c:27:
../src/cpu/cpu_x86.c: In function ‘virCPUx86DataIsIdentical’:
../src/util/virlog.h:79:5: error: ‘bdata’ may be used uninitialized in this
function [-Werror=maybe-uninitialized]
Fix this by just assigning the helper pointers and remove the condition
altogether.
