Backported several changes from kernel 2.6.19-git series

From: Mauro Carvalho Chehab <mchehab@infradead.org>

Main changes:

- There were several checks for usb release routines that were removed, since
  the routine itself checks for null values:
		usb_free_urb, usb_kill_urb, usb_unlink_urb
  Should be checked if this really happens on older kernels.
- updated sound/oss/btaudio.c
- replaced SLAB_ATOMIC to GFP_ATOMIC
