[0/3] 3 small cleanups for find_first_block_group

While trying to learn the Block Group code I've found some cleanup
possibilities for find_first_block_group().

Here's a proposal to make $ffbg a bit more easier to read by untangling the
gotos and if statements.

The patch set is based on misc-next from May 26 morning with 
HEAD 3f4a266717ed ("btrfs: split btrfs_direct_IO to read and write part")
and xfstests showed no regressions to the base misc-next in my test setup.

Johannes Thumshirn (3):
  btrfs: remove pointless out label in find_first_block_group
  btrfs: get mapping tree directly from fsinfo in find_first_block_group
  btrfs: factor out reading of bg from find_frist_block_group
