Add bounds checking to prevent overflow warnings during build.

[ciaran-moore]

Added bounds checking to util/src/inet.cpp to prevent overflow warnings during build.

Received the following warnings on Debian 12 when installing with the build command: cmake --preset Release -DPHP_SCYLLADB_OPTIMISE_FOR_CURRENT_MACHINE=ON -DPHP_SCYLLADB_USE_LIBCASSANDRA=ON -DPHP_SCYLLADB_LIBUV_STATIC=ON && cd out/Release && sudo ninja install
