[PATCH] tools: fix get_maintainers() returning None when no tree is found

[Ali Alnubani]

get_maintainers() only returned when the tree was found in the
"General Project Administration" section. If it was not found, the
function fell through and returned None, causing:

  TypeError: print() argument after * must be an iterable, not NoneType

Return the maintainers list (even if empty) at the end of the
function so callers always receive an iterable.
