bcachefs: optimize __bch2_trans_get(), kill DEBUG_TRANSACTIONS
- Some tweaks to greatly reduce locking overhead for the list of btree
transactions, so that it can always be enabled: leave btree_trans
objects on the list when they're on the percpu single item freelist,
and only check for duplicates in the same process when
CONFIG_BCACHEFS_DEBUG is enabled
- don't zero out the full btree_trans() unless we allocated it from
the mempool
