misc: pci_endpoint_test: Fix to support > 10 pci-endpoint-test devices

commit b5212d0eaf36bb77bdff1d15ddf6389bece50407 upstream.

Adding more than 10 pci-endpoint-test devices results in
"kobject_add_internal failed for pci-endpoint-test.1 with -EEXIST, don't
try to register things with the same name in the same directory". This
is because commit 83ae0721f861 ("misc: Add host side PCI driver for PCI
test function device") limited the length of the "name" to 20 characters.
Change the length of the name to 24 in order to support upto 10000
pci-endpoint-test devices.
