[LLDB] Remove the redundent 'properties' variable (#95675)

This is described in (N3) https://pvs-studio.com/en/blog/posts/cpp/1126/

Warning message -
V547 Expression 'properties ++ > 0' is always false.
CommandObjectTarget.cpp:100

I could not understand it properly but the properties++ operation is
performed twice when the target architecture is valid.
First increment seems unnecessary since it is always false '0>0'.
