[PATCH 05/42] bdev: Drop pointless invalidate_inode_buffers() call

Nobody is calling mark_buffer_dirty_inode() with internal bdev inode and
it doesn't make sense for internal bdev inode to have any metadata
buffer heads. Just drop the pointless invalidate_inode_buffers() call
and consequently the whole bdev_evict_inode() because generic code takes
care of the rest.
