Since hash() returns unsigned int, store results in unsigned ints

Clears clang warnings:
hash.c:82:13: warning: implicit conversion changes signedness: 'unsigned int' to 'int' [-Wsign-conversion]
    int i = hash(key);
        ~   ^~~~~~~~~
hash.c:94:13: warning: implicit conversion changes signedness: 'unsigned int' to 'int' [-Wsign-conversion]
    int i = hash(key);
        ~   ^~~~~~~~~
