firmware loader: fix build failure with !CONFIG_FW_LOADER_USER_HELPER
This patch fixes one build failure which is introduced by the patch
below:
driver core: firmware loader: kill FW_ACTION_NOHOTPLUG requests
before suspend
When CONFIG_FW_LOADER_USER_HELPER is unset, kill_requests_without_uevent()
should be nop because no userspace loading is involved.
