repair: request inode buffers sized to fit one inode cluster

In get_agino_buf, grab inode buffers using the same size as the inode
processing code.  Since the inode processing code uses that same
buffer size, this means that get_agino_buf can serve requests from the
cache instead of pointlessly dropping the cache entry and screaming
about it.
