[0/3] Cleanups in mount path

Following the misunderstanding around the 2nd argument of free_root_pointers it
became apparent that the relevant code in open_ctre is not entirely clear. That's
mainly due it being split among 2 labels, emulating a loop. This series 
cleans that up by factoring it out in a discrete function, init_root_trees in 
patch 1 and then subsequent patches implement  minor cleanups that became 
apparent while working with the code. 

This has survived full xfstest run. 

Nikolay Borisov (3):
  btrfs: Factor out tree roots initialization during mount
  btrfs: Don't use objectid_mutex during mount
  btrfs: Jump to correct label on init_root_trees failure
