Christophe Jaillet 74007ae631 hwmon: (xgene) Fix up error handling path mixup in 'xgene_hwmon_probe()' ...

Commit 2ca492e22c has moved the call to 'kfifo_alloc()' from after the
main 'if' statement to before it.
But it has not updated the error handling paths accordingly.

Fix all that:
   - if 'kfifo_alloc()' fails we can return directly
   - direct returns after 'kfifo_alloc()' must now go to 'out_mbox_free'
   - 'goto out_mbox_free' must be replaced by 'goto out', otherwise the
     '[pcc_]mbox_free_channel()' call will be missed.
