target-lm32: disable asm logging via LOG_DIS()

The lm32 target already has a disassembler which logs the assembly
instructions with "-d in_asm". Therefore, turn of the LOG_DIS() macro to
prevent logging the assembly instructions twice. Also turn the macro in a
one which is always compiled to catch any errors while the macro is turned
off.
