libxl: avoid infinite loop in libxl__remove_directory()

Infinitely retrying the rmdir() invocation makes little sense. While the
original observation was the log filling the disk (due to repeated
"Directory not empty" errors, in turn occurring for unclear reasons),
the loop wants breaking even if there was no error message being logged
(much like is done in the similar loops in libxl__remove_file() and
libxl__remove_file_or_directory()).
