msm: camera: Handling get buf properly when buffer queue is empty

There can be a possibility that the buffer queue is empty and
we ask for a buffer. In that case the address holding the buffer queue
structure data is not NULL but the entries of the structure are
NULL.

In such a case in addition to checking if bufq address is NULL,
when we request for a buffer, we also make sure that handle is
not NULL.

msm: camera: Maintain buffer queue in isp buf manager

we encountered a problem where we are trying to free one

Inorder to avoid this we are now maintaining a queue for
all the buffers during prepare buf and we unprepare only
if the buffer is present in this queue.
