virtcca bugfix: correct array copy for hpre_addr 

virtcca inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IB71ME



--------------------------------

virtCCA bugfix:The memcpy for 'params->hpre_addr' incorrectly used
'cfg->sec_addr' instead of 'cfg->hpre_addr',causing unintended data to
be copied.

Fixes: 46ff8325 ("virtcca feature : SM Cryptographic Aacceleration.")
