crypto: hisilicon/qm - fix PF queue parameter issue

Browse Source 
If the queue isolation feature is enabled, the number of queues
supported by the device changes. When PF is enabled using the
current default number of queues, the default number of queues may
be greater than the number supported by the device. As a result,
the PF fails to be bound to the driver.

After modification, if queue isolation feature is enabled, when
the default queue parameter is greater than the number supported
by the device, the number of enabled queues will be changed to
the number supported by the device, so that the PF and driver
can be properly bound.
