Btrfs: join the transaction in __btrfs_setxattr

Browse source 
With selinux on we end up calling __btrfs_setxattr when we create an inode,
which calls btrfs_start_transaction().  The problem is we've already called
that in btrfs_new_inode, and in btrfs_start_transaction we end up doing a
wait_current_trans().  If btrfs-transaction has started committing it will wait
for all handles to finish, while the other process is waiting for the
transaction to commit.  This is fixed by using btrfs_join_transaction, which
won't wait for the transaction to commit.  Thanks,
