Richard Yao 4170ae4ea6 Fix TOCTOU race conditions reported by CodeQL and Coverity ... CodeQL and Coverity both complained about: * lib/libshare/os/linux/smb.c * tests/zfs-tests/cmd/mmapwrite.c * twice * tests/zfs-tests/tests/functional/tmpfile/tmpfile_002_pos.c * tests/zfs-tests/tests/functional/tmpfile/tmpfile_stat_mode.c * coverity had a second complaint that CodeQL did not have * tests/zfs-tests/cmd/suid_write_to_file.c * Coverity had two complaints and CodeQL had one complaint, both differed. The CodeQL complaint is about the main point of the test, so it is not fixable without a hack involving `fork()`. The issues reported by CodeQL are fixed, with the exception of the last one, which is deemed to be a false positive that is too much trouble to wrokaround. The issues reported by Coverity were only fixed if CodeQL complained about them. There were issues reported by Coverity in a number of other files that were not reported by CodeQL, but fixing the CodeQL complaints is considered a priority since we want to integrate it into a github workflow, so the remaining Coverity complaints are left for future work.
