[PATCH 4/6] xfs: don't vmap inode cluster buffers during free

Dave Chinner

From: Dave Chinner <dchinner@redhat.com>

Inode buffers do not need to be mapped as inodes are read or written
directly from/to the pages underlying the buffer. This fixes a
regression introduced by commit 611c994 ("xfs: make XBF_MAPPED the
default behaviour").
