Subject: [PATCH AUTOSEL 5.17 03/43] crypto: hisilicon/qm - cleanup warning in qm_vf_read_qos

From: Kai Ye <yekai13@...wei.com>

[ Upstream commit 05b3bade290d6c940701f97f3233c07cfe27205d ]

The kernel test rebot report this warning: Uninitialized variable: ret.
The code flow may return value of ret directly. This value is an
uninitialized variable, here is fix it.
