fm10k: remove extraneous NULL check on l2_accel
fm10k: remove extraneous NULL check on l2_accel

l2_accel was checked for NULL at the top of fm10k_dfwd_del_station, and
we return if it is not defined. Due to this, we already know it can't be
null here so a separate check is meaningless. Discovered via cppcheck.
