cbtable: don't dereference memory that was previously unmapped

The backing store for 'head' was being unmapped prior to
dereferencing the variable. Don't do that, and calculate
the new mapping size prior to unmapping the previous table.

BUG=chromium:773801
BRANCH=none
TEST=Ran on parrot and didn't segfault.
