[lldb][nfc] Remove unused member Disassembler::m_base_addr

[bulbazord]

This member variable is completely unused. I also don't think it makes a ton of sense since (1) The "base address" can be obtained from the first Instruction in its InstructionList, and (2) InstructionLists may not be a series of contiguous instructions (even though they are most of the time).
