RISC-V: THEAD: Fix improper immediate value for MODIFY_DISP instruction on 32-bit systems.

When using  '%ld' to print 'long long int' variable, 'fprintf' will
produce messy output on a 32-bit system, in an incorrect instruction
being generated, such as 'th.lwib a1,(a0),-16,4294967295'. And the
following error occurred during compilation:

Assembler messages:
Error: improper immediate value (18446744073709551615)

gcc/ChangeLog:

	* config/riscv/thead.cc (th_print_operand_address): Change %ld
	to %lld.
