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

Browse Source 
[ Upstream commit 45e6319bd5 ]

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.
