ehea: fix error return code in ehea_restart_qps()

Browse Source 
[ Upstream commit 015dbf5662fd689d581c0bc980711b073ca09a1a ]

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.
