[PATCH] xfs_io: fix gcc-7 related printf warnings

[Dave Chinner <david@fromorbit.com>]

From: Dave Chinner <dchinner@redhat.com>

New compiler, new checks, new warnings.

Fix the new [-Wformat-truncation=] warnings that io/fsmap.c is
throwing w/ gcc-7.2 because "%lld..%lld" requires a buffer 40
characters long, not 32.
