Cast PL_dump_re_max_len to avoid type mismatch warning.

Specifically this one on VMS:

    || ! grok_atoUV(dump_len_string, &PL_dump_re_max_len, NULL))
.....................................^
%CC-W-PTRMISMATCH, In this statement, the referenced type of the
pointer value "&(my_perl->Idump_re_max_len)" is "unsigned int",
which is not compatible with "unsigned long".

This was new code in 2bfbbbaf9ef1783ba.
