ext2: Sync and invalidate metadata buffers from ext2_evict_inode()

Browse Source 
There are only very few filesystems using generic metadata buffer head
tracking and everybody is paying the overhead. When we remove this
tracking for inode reclaim code .evict will start to see inodes with
metadata buffers attached so write them out and prune them.
