vg_replace_malloc DELETE should not check size

vg_replace_malloc DELETE should not check size

The DELETE replacement functions check the size argument, but this
doesn't actually exist.  Only the DELETE_SIZED replacement functions
get a size (and should check it).

On i386 (fedora gnu/linux) this causes the following failures:

memcheck/tests/cxx17_aligned_new         (stderr)
memcheck/tests/leak_cpp_interior         (stderr)
memcheck/tests/mismatches                (stderr)
memcheck/tests/mismatches_xml            (stderr)
memcheck/tests/new_aligned_delete_default (stderr)
memcheck/tests/new_nothrow               (stderr)
memcheck/tests/realloc_size_zero_mismatch (stderr)

All showing "size" being undefined:

+Conditional jump or move depends on uninitialised value(s)
+   at 0x........: ...operator delete[]... (vg_replace_malloc.c:...)

or

+Mismatched new/delete size value: 4
+   at 0x........: ...operator delete... (vg_replace_malloc.c:...)

Oddly no other architecture seems to show issues. Maybe we just got lucky?

This patch fixes the issues on i386 (and shows no regressions on x86_64)
