ARM unwinder for thumb: Fix broken MOV opcode
The origin of the register value was never moved in the desired register state due to a typo ('rhs' vs. 'rhd'). While looking at the code, I noticed the action taken for the register value is another copy'n'paste error from the ADD opcode above -> it added to the register value instead of MOVing the current value. Patch submitted upstream. cppcheck reported: [lib/unwarminder/unwarm_thumb.c:473]: (warning) Redundant assignment of 'state.regData[rhd].o' to itself.
