[PATCH v2] bulk-checkin: fix sign compare warnings

[Tuomas Ahola <taahol@xxxxxx>]

In file bulk-checkin.c, three warnings are emitted by
"-Wsign-compare", two of which are caused by trivial loop iterator
type mismatches.  The third one is also an uncomplicated case for
which a simple cast is a safe and sufficient action as the variable in
question only holds positive values (from sizeof() expression).

Fix issues accordingly, and enable sign compare warnings for the file.
