[PATCH] btrfs: remove no longer used btrfs_transaction_in_commit()

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

The function btrfs_transaction_in_commit() is no longer used, its last
use was removed in commit 11aeb97b45ad ("btrfs: don't arbitrarily slow
down delalloc if we're committing"), so just remove it.
