Subject: [PATCH 2/6] autofs - fix clearing AUTOFS_EXP_LEAVES in
 autofs_expire_indirect()

The expire flag AUTOFS_EXP_LEAVES is cleared before the second
call to should_expire() in autofs_expire_indirect() but the
parameter passed in the second call is incorrect.

Fortunately AUTOFS_EXP_LEAVES expire flag has not been used for
a long time but might be needed in the future so fix it rather
than remove the expire leaves functionality.
