Fedor Pchelkin 6cc6f79b93 NFSv4/pnfs: minor fix for cleanup path in nfs4_get_device_info 
commit 96562c45af5c31b89a197af28f79bfa838fb8391 upstream.

It is an almost improbable error case but when page allocating loop in
nfs4_get_device_info() fails then we should only free the already
allocated pages, as __free_page() can't deal with NULL arguments.

Found by Linux Verification Center (linuxtesting.org).
