[PATCH 2/2] kernel32: Use RtlAnsiStringToUnicodeString() in OpenMutexA.

[Akihiro Sagawa]

This commit makes consistent with the commit 2db497e89e8e4a37a8bd569b8691b9b87ae63606,
which introduces RtlAnsiStringToUnicodeString() into CreateMutexA().

In multi-byte locale, suppose there is an odd ANSI string which ends with
leading-byte. MultiByteToWideChar() translates the last leading-byte to the
default character in Unicode nowadays (Vista+). However,
RtlAnsiStringToUnicodeString() remains old behavior which drops the last
leading-byte character when converting it to Unicode.

This difference confuses a certain application which uses binary string, i.e.
ill-formed multi-byte string, as a mutex name in Japanese locale.
