Lock channels only as necessary in dsp_ioctl(), and only lock one
channel at a time unless it is actually necessary to lock both.
This avoids problems with lock order reversal and malloc() calls
with a mutex held when lower level code unlocks a channel, calls malloc(),
and relocks the channel.  This also avoids the cost of some  unnecessary
locking and unlocking.
