[Qemu-devel] [PULL 6/8] cutils: remove one unnecessary pointer operation

[Juan Quintela <quintela@redhat.com>]

From: Wei Yang <richardw.yang@linux.intel.com>

Since we will not operate on the next address pointed by out, it is not
necessary to do addition on it.

After removing the operation, the function size reduced 16/18 bytes.
