I've recently seen this with valgrind while running the HMP tester:
==22373== Conditional jump or move depends on uninitialised value(s)

And indeed, in monitor_disas, the read_memory_inner_func variable was
not initialized, but arm_disas_set_info() expects this to be NULL
or a valid pointer. Let's properly set this to NULL in the
INIT_DISASSEMBLE_INFO to fix it in all functions that use the
disassemble_info struct.
