work around negated error code bug on some mips kernels
on all mips variants, Linux did (and maybe still does) have some syscall return paths that wrongly return both the error flag in r7 and a negated error code in r2. in particular this happened for at least some causes of ENOSYS. add an extra check to only negate the error code if it's positive to begin with. bug report and concept for patch by Andreas Dröscher.
