Stefan Hajnoczi d2fc39b420 qemu-char: avoid leaking unused fds in tcp_get_msgfds() 
Commit c76bf6bb8f ("Add chardev API
qemu_chr_fe_get_msgfds") extended the get_msgfds API from one to
multiple file descriptors.  It forgot to close unused file descriptors
before freeing the file descriptor array.

This patch prevents a file descriptor leak if the tcp_get_msgfds()
callers requests fewer file descriptors than are available.
