staging: kpc2000: fix error return code in kp2000_pcie_probe()
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")
