James Raphael Tiovalen f7b81034aa lib: sbi_pmu: Fix multiple start and stop operations of FW counters ...

Currently, OpenSBI returns SBI_ERR_ALREADY_STARTED when attempting to
start a HW counter that is already started and SBI_ERR_ALREADY_STOPPED
when attempting to stop a HW counter that is already stopped. However,
this is not yet implemented for FW counters.

Add the necessary checks to return the same error codes when attempting
the same actions on FW counters.
