net/ice/base: fix segment in remove existing RSS rule

Browse Source 
Before this patch, RSS tunneled rules can not be destroyed at runtime.
This is because it can not find the existing matching profile for tunnels.
segs[0] should always be zero and all matched, segs[1] for inner part.
It only construct one segment.

This patch modifies construct segment in ice_rem_rss_cfg_sync() to
match ice_add_rss_cfg_sync().

Fixes: b7d34ccc47 ("net/ice/base: packet encapsulation for RSS")
