ice: Extend Sideband Queue command to support flags

Current driver implementation for Sideband Queue supports a
fixed flag (ICE_AQ_FLAG_RD). To retrieve FEC statistics from
firmware, Sideband Queue command is used with a different flag.

Extend API for Sideband Queue command to use 'flags' as input
argument.
