Takashi Iwai 44f08b67f2 media: solo6x10: Convert to generic PCM copy ops
This patch converts the solo6x10 driver code to use the new unified
PCM copy callback.  It's a straightforward conversion from *_user() to
*_iter() variants.  As copy_to_iter() updates the internal offest at
each write, we can drop the dst counter update in the loop, too.

Note that copy_to_iter() returns the copied bytes, hence the error
condition is adjusted accordingly.
