xfs: do not take the iolock in xfs_inactive
An inode that enters xfs_inactive has been removed from all global lists but the inode hash, and can't be recycled in xfs_iget before it has been marked reclaimable. Thus taking the iolock in here is not nessecary at all, and given the amount of lockdep false positives it has triggered already I'd rather remove the locking. The only change outside of xfs_inactive is relaxing an assert in xfs_itruncate_extents.
