driver: soc: xilinx: fix memory leak in xlnx_add_cb_for_notify_event()
[ Upstream commit 1bea534991b9b35c41848a397666ada436456beb ]
The kfree() should be called when memory fails to be allocated for
cb_data in xlnx_add_cb_for_notify_event(), otherwise there will be
a memory leak, so add kfree() to fix it.
Fixes: 05e5ba40ea7a ("driver: soc: xilinx: Add support of multiple callbacks for same event in event management driver")
