Previously, the call to get_file_attribute for FIFOs set the first argument to NULL instead of the handle h returned by get_stat_handle, thereby forcing the file to be opened for fetching the security descriptor in get_file_sd(). This was done because h might have been a pipe handle rather than a file handle, and its permissions would not necessarily reflect those of the file. That situation can no longer occur with the new fhandler_fifo::fstat introduced in the previous commit.
