[PATCH] radix tree test suite: Fix incorrect allocation size for pthreads

[Colin Ian King]

Currently the pthread allocation for each array item is based on the
size of a pthread_t pointer and should be the size of the pthread_t
structure, so the allocation is under-allocating the correct size.
Fix this by using the size of each element in the pthreads array.

Static analysis cppcheck reported:
tools/testing/radix-tree/regression1.c:180:2: warning: Size of pointer
'threads' used instead of size of its data. [pointerSize]

Fixes: 1366c37ed84b ("radix tree test harness")
