[PATCH v4 1/8] pciehp: Make check_link_active() non-static

[Rajat Jain]

check_link_active() functionality needs to be used by subsequent patches
(that introduce link state change based hotplug). Thus make the function
non-static, and rename it to pciehp_check_link_active() so as to be
consistent with other non-static functions.
