PM / OPP: fix incorrect OPP count handling in of_init_opp_table

commit 086abb58590a4df73e8a6ed71fd418826937cd46 upstream.

In of_init_opp_table function, if a failure to add an OPP is
detected, the count of OPPs, yet to be added is not updated.
Fix this by decrementing this count on failure as well.
