commit c0d7d3e1a2 removed the usage of the
LCMAP_BYTEREV flag in the call to LCMapStringW to workaround a strange
bug in LCMapStringW. This patch didn't take a userspace call of
wcsxfrm{_l} with NULL buffer and 0 size to evaluate the required buffer
size into account. This introduced a crash trying to byte swap the
NULL buffer. This patch fixes that problem.
