libsepol: use correct error type to please UBSAN

Browse Source 
The callback function apply in hashtap_map has a return type of int and
can return -1 on error.  Use int as type to save the return value to
avoid implicit conversions:

    hashtab.c:236:10: runtime error: implicit conversion from type 'int' of value -1 (32-bit, signed) to type 'unsigned int' changed the value to 4294967295 (32-bit, unsigned)
