xfs: cap the block count of xfs_iomap_write_direct() at one extent
xfs_iomap_write_direct() reserves blocks for the whole count in an
unsigned int. For a pNFS layout the client chooses that count, and an
RW LAYOUTGET for 16 TiB wraps the reservation and shuts XFS down.
xfs_bmapi_write() maps at most XFS_MAX_BMBT_EXTLEN blocks here, so cap
the count at that. nfsd asks again for the rest. The other callers get
the same mapping as before.
