crypto: hisilicon/hpre - fix resource leak in remove process

[ Upstream commit 45e6319bd5f2154d8b8c9f1eaa4ac030ba0d330c ]

In hpre_remove(), when the disable operation of qm sriov failed,
the following logic should continue to be executed to release the
remaining resources that have been allocated, instead of returning
directly, otherwise there will be resource leakage.
