Make cam_periph_getccb() to simply allocate CCBs and consume device openings
neither checking their availability nor bothering with periph scheduling.
Consumers of this KPI are normally waiting on the CCB completion and so
number of CCBs there can't be infinite.  Finite number of CCBs can now be
correctly handled by the modified CCB queue code.

This allows to remove duplicated code needed to schedule allocation of these
immediate CCBs from many periph drivers, simplifying them and their locking.
