This mostly helps avoid some unnecessary enomem failures when logging
tree mod log operations and replace some BUG_ON()'s when dealing with
such failures. There's also 2 bug fixes (the first two patches) and
some cleanups. More details on the changelogs.

Filipe Manana (13):
  btrfs: add missing error handling when logging operation while COWing extent buffer
  btrfs: fix extent buffer leak after failure tree mod log failure at split_node()
  btrfs: avoid tree mod log ENOMEM failures when we don't need to log
  btrfs: do not BUG_ON() on tree mod log failure at __btrfs_cow_block()
  btrfs: do not BUG_ON() on tree mod log failure at balance_level()
  btrfs: rename enospc label to out at balance_level()
  btrfs: avoid unnecessarily setting the fs to RO and error state at balance_level()
  btrfs: abort transaction at balance_level() when left child is missing
  btrfs: abort transaction at update_ref_for_cow() when ref count is zero
  btrfs: do not BUG_ON() on tree mod log failures at push_nodes_for_insert()
  btrfs: do not BUG_ON() on tree mod log failure at insert_new_root()
  btrfs: do not BUG_ON() on tree mod log failures at insert_ptr()
  btrfs: do not BUG_ON() on tree mod log failures at btrfs_del_ptr()
