[PATCH AUTOSEL 5.6 171/606] staging: kpc2000: fix error return code in kp2000_pcie_probe()

From: Wei Yongjun <weiyongjun1@huawei.com>

commit b17884ccf29e127b16bba6aea1438c851c9f5af1 upstream.

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function. Also
removed var 'rv' since we can use 'err' instead.

Fixes: 7dc7967fc39a ("staging: kpc2000: add initial set of Daktronics drivers")
