[PATCH vRFC 7/8] firmware: remove prototype of fw_cache_piggyback_on_request()

[Mukesh Ojha <quic_mojha@quicinc.com>]

We should always try to avoid using prototype of a static
function like fw_cache_piggyback_on_request() firmware
main file. Move the relevant code in such a way that avoid
the prototype usage.
