Description

If spa_config_tryenter fails to acquire a particular lock, all locks that have been acquired in the mean time should be released. Unfortunately, the existing arithmetic in that case doesn't do that, so some locks can be left acquired.
Fix from Nexenta, originally reviewed internally by Alek Pinchuk and Josef 'Jeff' Sipek.
