Martin Sebor 764e9a0334 Correct buffer end pointer in IO_wdefault_doallocate (BZ #26874) 
An experimental build of GCC 11 with an enhanced -Warray-bounds
reports a bug in IO_wdefault_doallocate where the function forms
an invalid past-the-end pointer to an allocated wchar_t buffer
by failingf to consider the scaling by sizeof (wchar_t).

The fix path below corrects this problem.  It keeps the buffer
size the same as opposed to increasing it according to what other
code like it does.
