Subject: [PATCH net-next] ice: remove redundant null check on pf

From: Yunjian Wang <wangyunjian@...wei.com>

Before calling ice_set_dflt_mib(), the 'pf' has been dereferenced.
So the additional check is unnecessary, just remove it.

Addresses-Coverity: ("Dereference before null check")
Fixes: 7d9c9b791f9e ("ice: Implement LFC workaround")
