ALSA: wavefront: Proper check of get_user() error
The antient ISA wavefront driver reads its sample patch data (uploaded
over an ioctl) via __get_user() with no good reason; likely just for
some performance optimizations in the past. Let's change this to the
standard get_user() and the error check for handling the fault case
properly.
