sound: oss: Use kernel_read_file_from_path() for mod_firmware_load()
Since recently we have kernel_read_file_from_path(), and it's doing the same thing as our own home-baked mod_firmware_load(). Let's use the official API function and clean up the old code. Signed-off-by: Takashi Iwai <tiwai@suse.de>

- * mod_firmware_load - load sound driver firmware

- *
- * Load the firmware for a sound module (up to 128K) into a buffer.
- * The buffer is returned in *fp. It is allocated with vmalloc so is
- * virtually linear and not DMAable. The caller should free it with
- * vfree when finished.

- * The length of the buffer is returned on a successful load, the
