[sheepdog] [PATCH] sheep journal:fix the parameter type of 'size' passed to 'int prealloc(int fd, uint32_t size)'

[张灿群]

dear,
When i start sheep daemon with journal，the daemon couldn't start.
command:
sheep -j dir=/sdac,size=160G,skip=1  -l dir=/var/log/,level=err,format=server  /sdad/ -n -D -y 10.64.0.38 -p 7000 -c zookeeper:host-0-31:2181,host-0-32:2181,host-0-38:2181
debugino:
Apr 09 14:49:35  ERROR [main] prealloc(120) failed to preallocate space, Invalid argument
Apr 09 14:49:35  ERROR [main] prealloc(121) size is 0    // I printf the value
Apr 09 14:49:35  ERROR [main] create_journal_file(73) prealloc journal_file0 Invalid argument


so the value of 'size' was corrupted when the type changed.
