Btrfs: Make fallocate(2) more ENOSPC friendly

commit 5a303d5d4b8055d2e5a03e92d04745bfc5881a22 upstream.

fallocate(2) may allocate large number of file extents, so it's not
good to do it in a single transaction. This patch make fallocate(2)
start a new transaction for each file extents it allocates.
