Jens Axboe 87e5e6dab6 uio: make import_iovec()/compat_import_iovec() return bytes on success ...

Currently these functions return < 0 on error, and 0 for success.
Change that so that we return < 0 on error, but number of bytes
for success.

Some callers already treat the return value that way, others need a
slight tweak.
