Subject: [PATCH] RDMA/irdma: Remove unused irdma_cqp_*_fpm_val_cmd functions

From: "Dr. David Alan Gilbert" <linux@...blig.org>

irdma_cqp_commit_fpm_val_cmd() and irdma_cqp_query_fpm_val_cmd()
were added in 2021 by
commit 915cc7ac0f8e ("RDMA/irdma: Add miscellaneous utility definitions")
but haven't been used.

Remove them.

Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
