xfs: commit CoW-based atomic writes atomically
When completing a CoW-based write, each extent range mapping update is
covered by a separate transaction.
For a CoW-based atomic write, all mappings must be changed at once, so
change to use a single transaction.
Note that there is a limit on the amount of log intent items which can be
fit into a single transaction, but this is being ignored for now since
the count of items for a typical atomic write would be much less than is
typically supported. A typical atomic write would be expected to be 64KB
or less, which means only 16 possible extents unmaps, which is quite
small.
