ALSA: line6: use dynamic buffers

commit e5c812e84f0dece3400d5caf42522287e6ef139f upstream.

The line6 driver uses a lot of USB buffers off of the stack, which is
not allowed on many systems, causing the driver to crash on some of
them.  Fix this up by dynamically allocating the buffers with kmalloc()
which allows for proper DMA-able memory.
