[PATCH BlueZ 15/15] obexd: Fix not checking for valid fd on NewConnection

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

The fd needs to be checked as it may not be valid anymore which cause the
following warnings:

==8162== Warning: invalid file descriptor 1031 in syscall fcntl(DUPFD_CLOEXEC)()

(obexd:8162): GLib-WARNING **: giounix.c:412Error while getting flags for FD: Bad file descriptor (9)
