[PATCH] ice: Slightly simply ice_find_free_recp_res_idx

From: Christophe JAILLET
Date: Wed Nov 17 2021 - 16:21:30 EST

The 'possible_idx' bitmap is set just after it is zeroed, so we can save
the first step.

The 'free_idx' bitmap is used only at the end of the function as the
result of a bitmap xor operation. So there is no need to explicitly
zero it before.

So, slightly simply the code and remove 2 useless 'bitmap_zero()' call

I don't think it will make any differences in RL. ICE_MAX_FV_WORDS is
just 48 (bits), so 1 or 2 longs
