[PATCH 1/1] ehea: fix error return code in ehea_restart_qps()

Fix to return -EFAULT from the error handling case instead of 0, as done
elsewhere in this function.

By the way, when get_zeroed_page() fails, directly return -ENOMEM to
simplify code.

Fixes: 2c69448bbced ("ehea: DLPAR memory add fix")
