Russell, this fixes xfs_iext_irec_compact_full(). If we don't move
all the records from the next page into the current page then we need
to update the er_extoff of the modified page as we move the remaining
extents up. Would you mind giving it a go?

Lachlan, I concur. I spent way too long last night looking at this and
arrived at the same conclusion about the root cause of the problem, but
didn't hae *quite* the right solution. I blame it on 2am ;) Your fix
(though I'd probably move the erp_next changes into the else clause?
Otherwise you're changing it then freeing it.)
