tcg: Fix compiler error (comparison of unsigned expression)
When qemu is configured with --enable-debug-tcg,
gcc throws this warning (or error with -Werror):
tcg/tcg.c:1030: error: comparison of unsigned expression >= 0 is always true
Fix it by removing the >= 0 part.
The type cast to 'unsigned' catches negative values of op
(which should never happen).
This is a modification of Hollis Blanchard's patch.
