[ Upstream commit e1e54ec7fb55501c33b117c111cb0a045b8eded2 ]

In commit 99cd149efe82 ("sgiseeq: replace use of dma_cache_wback_inv"),
a call to 'get_zeroed_page()' has been turned into a call to
'dma_alloc_coherent()'. Only the remove function has been updated to turn
the corresponding 'free_page()' into 'dma_free_attrs()'.
The error hndling path of the probe function has not been updated.

Fix it now.

Rename the corresponding label to something more in line.
