* subversion/libsvn_fs/fs-loader.c
  (get_library_vtable_direct, svn_fs_create, svn_fs_open,
   svn_fs_recover, svn_fs_create_berkeley, svn_fs_open_berkeley):
  Change prioritization of error returned if we get a mutex-release
  error as well as an error from the serialized function call.  The
  function call error will be returned.  Also corrected an
  indentation mistake.
