[PATCH 27/37] db: re-enable write support for v5 filesystems.

[Dave Chinner]

From: Dave Chinner <dchinner at redhat.com>

As we can now verify and recalculate CRCs on IO, we can modify the
on-disk structures without corrupting the filesyste, This makes it
safe to turn write support on for v5 filesystems for the first time.
