[dpdk-dev] [PATCH v2] raw/ifpga_rawdev: fix fd leak in rte fpga do pr

[Andy Pei <andy.pei@intel.com>]

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

Coverity issue: 279441
Fixes: ef1e8ede3da5 ("raw/ifpga: add Intel FPGA bus rawdev driver")
