Johannes Thumshirn 373c3b80e4 btrfs: don't leak extent_map in btrfs_get_io_geometry() 
btrfs_get_io_geometry() calls btrfs_get_chunk_map() to acquire a reference
on a extent_map, but on normal operation it does not drop this reference
anymore.

This leads to excessive kmemleak reports.

Always call free_extent_map(), not just in the error case.
