qcacmn: Fix number of active command timers in psoc

In psoc open, driver try to get the number of PDEV and
allocate memory for number of timers. But during psoc open number of
pdev are 0, thus timers is not allocated for non scan active queues.

Now if all scan active queues are full and a non scan command is
activated, it tries to find empty timer, which is not found, as
all timers are used by scan commands. Thus timer is not started for
this command and when this command is aborted the timer destroy API
return failure and thus the command is not removed from the active
queue.

Allocate the timer during psoc enable where pdevs are already created
and driver can get the number of pdev and print error if start timer
fails for a command.
