Christoph Hellwig b784951662 iomap: move locking out of iomap_write_delalloc_release

XFS (which currently is the only user of iomap_write_delalloc_release)
already holds invalidate_lock for most zeroing operations.  To be able
to avoid a deadlock it needs to stop taking the lock, but doing so
in iomap would leak XFS locking details into iomap.

To avoid this require the caller to hold invalidate_lock when calling
iomap_write_delalloc_release instead of taking it there.
