Revert "OPP: fix dev_pm_opp_find_bw_*() when bandwidth table not initialized"

Browse Source 
This reverts commit 8532fd078d which is
commit b44b9bc7cab2967c3d6a791b1cd542c89fc07f0e upstream.

It breaks the Android kernel abi and can be brought back in the future
in an abi-safe way if it is really needed.
