soundcore_open: Reduce the area BKL coverage
Most of this function is protected by the sound_loader_lock. We can push down the BKL to this call out err = file->f_op->open(inode,file); In order to build the sound core without the BKL, we will need to push the lock_kernel() call into the ~20 device drivers that register their file operations.
