Subject[PATCH 5.5 113/150] ice: Remove possible null dereference
Date
From: Tony Nguyen <anthony.l.nguyen@intel.com>

commit 0a6ea04e3bbd20833d2b49296e5adc1c5bb86386 upstream.

Commit 1f45ebe0d8fb ("ice: add extra check for null Rx descriptor") moved
the call to ice_construct_skb() under a null check as Coverity reported a
possible use of null skb. However, the original call was not deleted, do so
now.
