[SDK:WINE] Fix get_temp_buffer() call in wine_dbgstr_wn()

Addendum to commit dbc7eeb47e (PR #4303).

The argument to get_temp_buffer() should specify the length of the
string being buffered + 1 (for the NUL-terminator).
The original code wrongly interverted this with specifying the buffer
shifted by one character.
