target-mips: Remove assignment to a variable which is never used

This assignment causes a compiler warning for compilations with the compiler
option -Wunused-but-set-variable (which is included with -Wextra).

Removing it allows using -Wextra for QEMU code without suppressing too many
extra warnings.
