crypto: hisilicon/qm - centralize the sending locks of each module into qm
[ Upstream commit 8cd9b608ee8dea78cac3f373bd5e3b3de2755d46 ]
When a single queue used by multiple tfms, the protection of shared
resources by individual module driver programs is no longer
sufficient. The hisi_qp_send needs to be ensured by the lock in qp.
Fixes: 5fdb4b345cfb ("crypto: hisilicon - add a lock for the qp send operation")
