bus/ifpga: remove useless check while browsing devices

[ upstream commit 62c21c3 ]

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: 05fa3d4 ("bus/ifpga: add Intel FPGA bus library")
