winreg: Use the ntstatus return code for client side errors

cli_winreg.c functions indicate status to the caller in two ways. The
ntstatus return code indicates client side errors, the pwerr argument
carries the server response error code.

Many functions are filling the pwerr argument on client side error, this
change removes these cases.
