[PATCH 3.19.y-ckt 175/210] Btrfs: clean up an error code in btrfs_init_space_info()

[Kamal Mostafa]

3.19.8-ckt14 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

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')
