Subject: [PATCH] ubifs: Remove a redundant null check on pointer lp

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

An earlier fix to replace an IS_ERR check on lp with a null check
on lp didn't remove a following null check on lp. The second null
check is redundant and can be removed.

Addresses-Coverity: ("Logically dead code")
Fixes: c770cd5190ba ("ubifs: fix an IS_ERR() vs NULL check")
