[PATCH V2] xfstests: fix error msg in aio-dio-subblock-eof-read.c

[Eric Sandeen <sandeen@xxxxxxxxxxx>]

io_getevents returns the number of events; printing its
return as "bytes read" is ... wrong.

Signed-off-by: Eric Sandeen <sandeen@xxxxxxxxxx>

V2: print as signed so we can easily see errors returned
