Print informations even on short reads. Bug 9310 (https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9310)

Before this patch, an error message would be printed when the file
appears to be truncated. After this patch, a warning will be printed,
but the information is still displayed. In both cases, capinfos exits
with status code 1.
