ice: fix over-shifted variable

Browse Source 
commit 242e34500a32631f85c2b4eb6cb42a368a39e54f upstream.

Since the introduction of the ice driver the code has been
double-shifting the RSS enabling field, because the define already has
shifts in it and can't have the regular pattern of "a << shiftval &
mask" applied.

Most places in the code got it right, but one line was still wrong. Fix
this one location for easy backports to stable. An in-progress patch
fixes the defines to "standard" and will be applied as part of the
regular -next process sometime after this one.
