[PATCH] ntdll: Zero init reg_tzi in find_reg_tz_info().

[Paul Gofman]

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=48694

Zero init does not affect the search itself but the structure
is also copied to input / output variable and the application
seems to be unhappy with the random data beyond the end of
strings.
