Chenghai Huang a87a21a562 crypto: hisilicon/qm - set NULL to qm->debug.qm_diff_regs
[ Upstream commit f0cafb02de ]

When the initialization of qm->debug.acc_diff_reg fails,
the probe process does not exit. However, after qm->debug.qm_diff_regs is
freed, it is not set to NULL. This can lead to a double free when the
remove process attempts to free it again. Therefore, qm->debug.qm_diff_regs
should be set to NULL after it is freed.
