crypto: hisilicon/qm - fix incorrect parameters usage

[ Upstream commit f57e292897cac13b6ddee078aea21173b234ecb7 ]

In qm_get_xqc_depth(), parameters low_bits and high_bits save
the values of the corresponding bits. However, the values saved by the
two parameters are opposite. As a result, the values returned to the
callers are incorrect.
