Revert "module: delay kobject uevent until after module init call"

This reverts commit c5891b73.

This patch causes changed timings during module init and sometimes
breaks wifi init. In that case /sys/module/wlan/parameters/fwpath
doesn't exist yet in the function wifi_change_fw_path in
frameworks/opt/net/wifi and we get a "Permission denied" error.

Reverting this patch fixes the behavior.
