[RESEND PATCH] nfs: Remove unnecessary NULL check before kfree()

[Thorsten Blum]

Since kfree() already checks if its argument is NULL, an additional
check before calling kfree() is unnecessary and can be removed.

Remove it and thus also the following Coccinelle/coccicheck warning
reported by ifnullfree.cocci:

  WARNING: NULL check before some freeing functions is not needed
