[PATCH] arch: m68k: math-emu: unsigned issue, 'unsigned long' willnever be less than zero.

[Chen Gang]

'oldmant.m32[1]' is 'unsigned long' which never '< 0', and the original
author wanted to check the highest bit whether set.

So need type cast form 'unsigned long' to 'long'.

The related warning: (with EXTRA_CFLAGS=-W ARCH=m68k for allmodconfig)
  arch/m68k/math-emu/fp_arith.c:522:4: warning: comparison of unsigned expression >= 0 is always true [-Wtype-limits]
