libcopybit: Fix potential memory and surface leaks in c2d
- Check MAX_SURFACES while mapping GPU addr
--- While mapping gpu address, first check if the request
is less than the MAX_SURFACES allowed.
--- Without this check, when the request exceeded MAX_SURFACES,
there was memory leak as that gpu addr was not unmapped
- Map the destination surface only once
--- The destination surface for the c2d blit will be the
FRAME_BUFFER_TARGET per transaction
--- Map this only once from the copybit_clear which is the first
call by hwc for a transaction
- Increase MAX_RGB_SURFACES to 12
--- To handle use cases where there are more than 8 RGB layers
