Modified Files:
        src/sys/kern: vfs_wapbl.c
        src/sys/sys: wapbl.h
        src/sys/ufs/ffs: ffs_inode.c ffs_wapbl.c
        src/sys/ufs/ufs: ufs_wapbl.h

Log Message:
during truncate with wapbl, register deallocation for upper indirect block
before recursing into lower blocks, to make sure that it will be removed after
all its referenced blocks are removed

fixes 'ffs_blkfree_common: freeing free block' panic triggered by
ufs_truncate_retry() when just the upper indirect block registration failed,
code tried to free the lower blocks again after wapbl flush

problem found by hannken@, thank you
