MINOR: hlua: fix return type for hlua_checkfunction() and hlua_checktable()

Browse Source 
hlua_checktable() and hlua_checkfunction() both return the raw
value of luaL_ref() function call.
As luaL_ref() returns a signed int, both functions should return a signed
int as well to prevent any misuse of the returned reference value.
