io: error_prepend() in qio_channel_readv_full_all() causes segfault
Using error_prepend() in qio_channel_readv_full_all() causes a segfault
as errp is not set when ret is 0. This results in the failure of iotest
83. Replacing with error_setg() fixes the problem.
Additionally, removes a full stop at the end of error message

(io: add qio_channel_readv_full_all_eof & qio_channel_readv_full_all helpers)
