[sheepdog] [PATCH] sheep: fix to handle the variable type of data_length

[Teruaki Ishizaki]

Previously, data_length was handled as integer in some places.
But, data_length of a request/response data type is uint32_t,
so there were some bad behaviors.

This patch fixes to handle data_length as uint32_t.
