Corinna Vinschen 10900b98d1 Cygwin: wcsxfrm_l: Only byte swap if dest size is > 0
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.
