avoid double close() and EBADF
It can be dangerous to hit (and ignore) EBADF errors in
multi-threaded applications. Users of POSIX_MQ#to_io have two
Ruby objects pointing to the same file descriptor, making
things tricky when it comes time to reap resources.
We'll always prefer to close the Ruby IO object if it exists
(because we have less control over its GC behavior) and
ignore the raw descriptor.
