[PATCH] ice/base: fix gcc 12 warning stringop-overflow

[wenxuanx.wu@intel.com]

From: Wenxuan Wu <wenxuanx.wu@intel.com>

Gcc with -O2 flag, would retrieve the value in one time.
This patch changed the type of fv_idx in struct ice_recp_grp_entry to
align with its callers which is also u8 type.

When u8 idx[5] = a value u16 index[4], gcc12 would give this warning,
because it is not big enough to store the bytes(bigger than 5 bytes)
in one time (-O2 would do it in this way).

Fixes: 04b8ec1ea807 ("net/ice/base: add protocol structures and defines")
