Subject: Btrfs: clean up an error code in btrfs_init_space_info()
commit 0dc924c5f2a3c4d999e12feaccee5f970cea1315 upstream.
If we return 1 here, then the caller treats it as an error and returns
-EINVAL. It causes a static checker warning to treat positive returns
as an error.
Fixes: 1aba86d67f34 ('Btrfs: fix easily get into ENOSPC in mixed case')
