Build failure in CI test due to HostPtr=null in memcpy

[asudarsa]

Describe the bug
In sycl/source/detail/sycl_mem_obj_t.hpp, there is a memcpy call that fails during build as follows:
[2023-07-14T04:10:16.104Z] /netbatch/donb1156623_00/runDir/jenkins-dir/workspace/SYCL_CI/intel/Build_PR_RHEL/llvm.src/sycl/source/detail/sycl_mem_obj_t.hpp:195:18: error: argument 2 null where non-null expected [-Werror=nonnull]
This failure is seen in #10379 which has only test update.

Additional context
#10334 seems to be a possible reason.
