Removed OSSlib stuff from linux/soundcard.h to fix the warnings for 'make headers_check'. This patch breaks building against OSSlib with the kernel headers instead of its own headers. It should still work with any version of the library from the 2003 onwards which provide their own headers for the latest interface.
