[dpdk-dev] [PATCH] raw/ifpga: fix fd leak in rte fpga do pr

[Andy Pei]

In rte_fpga_do_pr() function, if 'stat' returns error,
rte_fpga_do_pr() returns -EINVAL without closing the
'file_fd' that has been opened.
After this patch, 'file_fd' is closed before rte_fpga_do_pr()
returns -EINVAL when 'stat' returns error
