Konstantin Belousov 5c76452f8f Mark the filedescriptor table entries with VOP_OPEN being performed for them ...

as UF_OPENING. Disable closing of that entries. This should fix the crashes
caused by devfs_open() (and fifo_open()) dereferencing struct file * by
index, while the filedescriptor is closed by parallel thread.
