Never call unmap with MAP_FAILED. (#5590)
When mmap is called, the code in correctly checks for p == MAP_FAILED.
But the resource cleanup at the end of busname_peek_message checks for
p == NULL, and if that's not true, munmap is called.
Therefore in error case, munmap is called with a MAP_FAILED argument
which can result in unexpected behaviour depending on sz's value.
