From: Nenghua Cao <nhcao@marvell.com>

It fixes the following case:
Two FEs connects the same BE; FE1 & BE path has been opened and hw_paramed.
At this momment, FE2 & BE path is being opened and hw_paramed. The BE
dai will do hw_param again even if it has done hw_param. It is not
reasonable.
FE1------------>BE
FE2-------------^
