net: rps: fix error when CONFIG_RFS_ACCEL is off

Browse Source 
John Sperbeck reported that if we turn off CONFIG_RFS_ACCEL, the 'head'
is not defined, which will trigger compile error. So I move the 'head'
out of the CONFIG_RFS_ACCEL scope.

Fixes: 84b6823cd9 ("net: rps: protect last_qtail with rps_input_queue_tail_save() helper")
