[PATCH 1/2] firmware: stratix10-svc: add missing gen_pool_destroy() in stratix10_svc_drv_probe()

[Dinh Nguyen]

From: Yang Yingliang <yangyingliang@xxxxxxxxxx>

In error path in stratix10_svc_drv_probe(), gen_pool_destroy() should be called
to destroy the memory pool that created by svc_create_memory_pool().

Fixes: 7ca5ce896524 ("firmware: add Intel Stratix10 service layer driver")
