ext4: flush the extent status cache during EXT4_IOC_SWAP_BOOT

commit cde2d7a796f7e895e25b43471ed658079345636d upstream.

Previously we weren't swapping only some of the extent_status LRU
fields during the processing of the EXT4_IOC_SWAP_BOOT ioctl.  The
much safer thing to do is to just completely flush the extent status
tree when doing the swap.
