Fix z_teardown_inactive_lock deadlock
When rolling back a mounted filesystem zfs_suspend() is called
which acquires the z_teardown_inactive_lock. This lock can not
be dropped until the filesystem has been rolled back and resumed
in zfs_resume_fs().
Therefore, we must not call iput() under this lock because it
may result in the inode->evict() handler being called which also
takes this lock. Instead use zfs_iput_async() to ensure dropping
the last reference is deferred and runs in a safe context.
