eal/linux: fix build with extra pci config

Build log:
	lib/librte_eal/common/eal_common_pci.c:188:4: error:
	implicit declaration of function pci_config_space_set

The function rte_eal_pci_probe_one_driver, which calls
pci_config_space_set, was moved to eal_common_pci.c,
but pci_config_space_set was left in eal_pci.c with static specifier.

Fixes: 4d4ebca4 ("pci: merge probing and closing functions for linux and bsd")
