btrfs: do proper error handling in create_reloc_root
[ Upstream commit 84c50ba5214c2f3c1be4a931d521ec19f55dfdc8 ]
We do memory allocations here, read blocks from disk, all sorts of
operations that could easily fail at any given point. Instead of
panicing the box, simply return the error back up the chain, all callers
at this point have proper error handling.
