Subject: [PATCH] hippi: Fix a size used in a 'pci_free_consistent()' in an error handling path

The size used when calling 'pci_alloc_consistent()' and
'pci_free_consistent()' should match.

Fix it and have it consistent with the corresponding call in 'rr_close()'.

Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
