Subject: [PATCH] libopeniscsiusr: Compare with max int instead of max long

This compares value member of int_list_tbl struct which is of unsigned
int type.

struct int_list_tbl {
const char *name;
unsigned int value;
};

Clang compiler reports this comparison when
-Wtautological-constant-out-of-range-compare is enabled

| idbm.c:1042:2: error: result of comparison of constant 18446744073709551615 with expression of type 'unsigned int' is always true [-Werror,-Wtautological-constant-out-of-range-compare]

|                     ~~~~~~~~~~~~~~~ ^  ~~~~

Since max value for int can be less than unsinged long e.g. on LP64 its
better to use UINT_MAX here
