PCI: endpoint: Fix WARN() when an endpoint driver is removed

Since there is no release callback defined for the PCI EPC device,
the below warning is thrown by driver core when a PCI endpoint driver is
removed:

  Device 'e65d0000.pcie-ep' does not have a release() function, it is broken and must be fixed. See Documentation/core-api/kobject.rst.
  WARNING: CPU: 0 PID: 139 at drivers/base/core.c:2232 device_release+0x78/0x8c

Hence, add the release callback and also move the kfree(epc) from
pci_epc_destroy() so that the epc memory is freed when all references are
dropped.
