Btrfs: don't call btrfs_throttle in file write
Btrfs_throttle will make us wait if there is a currently committing transaction until we can open new transactions, which is ridiculous since we don't actually start any transactions within the file write path anyway, so all this does is introduce big latencies if we have a sync/fsync heavy workload going on while somebody else is trying to do work.
