[PATCH] nfsd: remove redundant assignment to pointer 'this'

[PATCH] nfsd: remove redundant assignment to pointer 'this'

[Colin King]

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

The pointer 'this' is being initialized with a value that is never read
and it is being updated later with a new value. The initialization is
redundant and can be removed.
