target-mips: fix call to memset in soft reset code

Recent versions of GCC report the following error when compiling
target-mips/helper.c:

  qemu/target-mips/helper.c:542:9: warning: ‘memset’ used with length
  equal to number of elements without multiplication by element size
  [-Wmemset-elt-size]

This is indeed correct and due to a wrong usage of sizeof(). Fix that.
