Wrong value of ov_index resulted in magic check failure, and refuse to
free() the memory allocated with __crt_aligned_alloc_offset().
Then the TLS segments of exited threads leaked.

It is modelled after aligned_alloc(3). Most importantly, to free the
allocation, __crt_free() can be used. Additionally, caller may specify
offset into the aligned allocation, so that we return offset-ed from
alignment pointer.
