Fix the ssetmask() system call by removing the invocation of sigorset(). The ssetmask() system call should replace the old signal mask with the new and return the old mask. It shouldn't combine the old and the new mask with sigorset(). Fetching the old mask for sigorset() is also no longer needed. The problem was detected after running LTP test group syscalls for the MIPS EL 32 R2 architecture where the test ssetmask01 failed with exit code 1. The test passes now that the ssetmask() system call is fixed.
