[PATCH 01/13] btrfs: don't get an EINTR during drop_snapshot for reloc

[Josef Bacik]

This was partially fixed by f3e3d9cc35252, however it missed a spot when
we restart a trans handle because we need to end the transaction.  The
fix is the same, simply use btrfs_join_transaction() instead of
btrfs_start_transaction() when deleting reloc roots.
