crypto: hisilicon - change parameter passing of debugfs function

mainline inclusion
from mainline-master
commit 74f5edbf
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I475PF?from=project-issue
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/herbert/cryptodev-2.6.git/commit/?id=74f5edbffcd37162084b6883e059bb6bb686151d

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

To avoid repeatedly obtaining 'qm' from 'filp', parameter passing of
debugfs function directly use 'qm' instead of 'filp'.
