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 Reported-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Jagannathan Raman <jag.raman@oracle.com> Fixes: bebab91ebdfc591f8793a9a17370df1bfbe8b2ca (io: add qio_channel_readv_full_all_eof & qio_channel_readv_full_all helpers) Message-Id: <be476bcdb99e820fec0fa09fe8f04c9dd3e62473.1613128220.git.jag.raman@oracle.com> Reviewed-by: Daniel P.
