ext4: Fix BUG_ON at fs/buffer.c:652 in no journal mode
Calls to ext4_handle_dirty_metadata should only pass in an inode pointer for inode-specific metadata, and not for shared metadata blocks such as inode table blocks, block group descriptors, the superblock, etc. The BUG_ON can get tripped when updating a special device (such as a block device) that is opened (so that i_mapping is set in fs/block_dev.c) and the file system is mounted in no journal mode.
