3cc2a4f7c9 sem_holder: Fixes improper restoration of base_priority 
in the case of CONFIG_SEM_PREALLOCHOLDERS=0

   The call to sem_restorebaseprio_task context switches in the
   sem_foreachholder(sem, sem_restoreholderprioB, stcb); call
   prior to releasing the holder. So the running task is left
   as a holder as is the started task. Leaving both slots filled
   Thus failing to perforem the boost/or restoration on the
   correct tcb.

   This PR fixes this by releasing the running task slot prior
   to reprioritization that can lead to the context switch.
   To faclitate this, the interface to sem_restorebaseprio
   needed to take the tcb from the holder prior to the
   holder being freed. In the failure case where sched_verifytcb
   fails it added the overhead of looking up the holder.

   There is also the adfitinal thunking on the foreach to
   get from holer to holder->tcb.

   An alternate approach could be to leve the interface the same
   and allocate a holder on the stack of sem_restoreholderprioB
   copy the sem's holder to it, free it as is done in this pr
   and and then pass that address sem_restoreholderprio as the
   holder. It could then get the holder's tcb but we would
   keep the same sem_findholder in sched_verifytcb.
