crypto: hisilicon/qm - check whether the input function and PF are on the same device
[ Upstream commit 6a2c9164b52e6bc134127fd543461fdef95cc8ec ]
Function rate limiting is set through physical function driver.
Users configure by providing function information and rate limit values.
Before configuration, it is necessary to check whether the
provided function and PF belong to the same device.
