[PATCH] nilfs2: remove redundant pointer sbufs

[Ryusuke Konishi <konishi.ryusuke@gmail.com>]

From: Colin Ian King <colin.i.king@gmail.com>

Pointer sbufs is being assigned a value but it's not being used
later on. The pointer is redundant and can be removed. Cleans up
scan-build static analysis warning:

fs/nilfs2/page.c:203:8: warning: Although the value stored to 'sbufs'
is used in the enclosing expression, the value is never actually read
from 'sbufs' [deadcode.DeadStores]
        sbh = sbufs = page_buffers(src);
