[PATCH] perf tests: Do not use sizeof on pointer type

[Vaishali Thakkar <vaishali.thakkar@oracle.com>]

Using sizeof on a malloced pointer type will return the wordsize
which can often cause one to allocate a buffer much smaller than
it is needed. So, here do not use sizeof on pointer type.

Note that this has no effect on runtime because 'dsos' is a
pointer to a pointer.

Problem found using Coccinelle.
