ubifs: remove broken lazytime support

[ Upstream commit ecf84096a526f2632ee85c32a3d05de3fa60ce80 ]

When "ubifs: introduce UBIFS_ATIME_SUPPORT to ubifs" introduced atime
support to ubifs, it also added lazytime support.  As far as I can tell
the lazytime support is terminally broken, as it causes
mark_inode_dirty_sync to be called from __writeback_single_inode, which
will then trigger the locking assert in ubifs_dirty_inode.  Just remove
the broken lazytime support for now, it can be added back later,
especially as some infrastructure changes should make that easier soon.
