qcacld-3.0: Replace Linux Fix-Width data-type with C-99 stdints

Protocol stack supposed to be HLOS-agnostic, but there is some use of
Linux fixed-width types u8, u16, and u32. These should be replaced with
C99 fixed-width types uint8_t, uint16_t, and uint32_t so that they will
correctly be HLOS-agnostic and work on non-Linux targets.
