[PATCH] xfs: propagate errors from xfs_rtginode_load

[Guanghui Yang]

xfs_rtginode_ensure() treats every xfs_rtginode_load() error other than
-ENOENT as success.  This can leave the realtime group inode unset after an
I/O, allocation, or corruption error.  Growfs then continues as though the
inode had been loaded.

Only -ENOENT means that the inode needs to be created.  Return all other
errors to the growfs caller.
