[PATCH] bus/ifpga: remove useless check while browsing devices

[Maxime Gouin <maxime.gouin@6wind.com>]

reported by code analysis tool C++test (version 10.4):

> /build/dpdk-20.11/drivers/bus/ifpga/ifpga_bus.c
> 67    Condition "afu_dev" is always evaluated to true
> 81    Condition "afu_dev" is always evaluated to true

The "for" loop already checks that afu_dev is not NULL.

Fixes: 05fa3d4a6539 ("bus/ifpga: add Intel FPGA bus library")
