Damien Le Moal 74955851ad PCI: endpoint: Fix configfs group removal on driver teardown 
commit 910bdb8197 upstream.

An endpoint driver configfs attributes group is added to the
epf_group list of struct pci_epf_driver by pci_epf_add_cfs() but an
added group is not removed from this list when the attribute group is
unregistered with pci_ep_cfs_remove_epf_group().

Add the missing list_del() call in pci_ep_cfs_remove_epf_group()
to correctly remove the attribute group from the driver list.

With this change, once the loop over all attribute groups in
pci_epf_remove_cfs() completes, the driver epf_group list should be
empty. Add a WARN_ON() to make sure of that.
