flowcache: more "unsigned int"
Make ->hash_count, ->low_watermark and ->high_watermark unsigned int
and propagate unsignedness to other variables.
This change doesn't change code generation because these fields aren't
used in 64-bit contexts but make it anyway: these fields can't be
negative numbers.
