[tarantool-patches] [PATCH] Don't free fiber gc on while txn_rollback

[Georgy Kirichenko <georgy@tarantool.org>]

In some cases volatile memory should be usable after txn_rollback
invocation. So move fiber_gx to the box_txn_rollback from the
txn_rollback.

Follow-up
  77fa1736dbb9 box: factor fiber_gc out of txn_commit
