partx: fix const qualifier warning in get_max_partno

Fix const qualifier discarded warning in get_max_partno().
This warning is reported by gcc 15 which defaults to the C23 standard.

The strrchr() function returns a pointer into a const string, so the
receiving variable must be declared as const char *.
