bcachefs: Improve trace_trans_restart_upgrade

Browse source

- Convert to a 'fs_str' tracepoint that just emits as a string: this
  lets us build up the tracepoint with a printbuf, using our pretty
  printers, and they're much easier to manage

- Include locks_held, before and after

- Include the btree node pointer we failed on (error pointer, null, or
  real node)
