btrfs: Change the hole range to a more accurate value.

Commit b56885545be1c3279a31e2da4819fa68c44d2223 fixed the btrfs expanding
write problem but the hole punched is sometimes too large for some
iovec, which has unmapped data ranges.
This patch will change to hole range to a more accurate value using the
counts checked by the write check routines.
