ALSA: Align the syntax of iov_iter helpers with standard ones

We introduced a couple of helpers for copying iomem over iov_iter, and
the functions were formed like the former copy_from/to_user(), and the
return value was adjusted to 0/-EFAULT, which made the code transition
a bit easier at that time.

OTOH, the standard copy_from/to_iter() functions have different
argument orders and the return value, and this difference can be
confusing. It's not only confusing but dangerous; actually I did
write a wrong code due to that once :-<

For reducing the confusion, this patch changes the syntax of those
helpers to align with the standard copy_from/to_iter(). The argument
order is changed and the return value is the size of copied bytes.
The callers of those functions are updated accordingly, too.

ALSA: core: Add memory copy helpers between iov_iter and iomem

Add two more helpers for copying memory between iov_iter and iomem,
which will be used by the new PCM copy ops in a few drivers.
The existing helpers became wrappers of those now.

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

- replaced __nocast uses for gfp flags with gfp_t - it gives exactly

3.2GB when imported into git - space that would just make the early

infrastructure for it.
