Cygwin: drop path_conv::reset_conv_handle
path_conv::reset_conv_handle is only called after fhandler::copyto
has been called. This duplicated the path_conv_handle if there was
one, so just setting the conv handle to NULL potentially produces a
handle leak. Replace reset_conv_handle calls with calls to
close_conv_handle and drop the reset_conv_handle method.
