Konstantin Belousov 47d81c1b70 Postpone dropping fp till both kq_global and kqueue mutexes are ...

unlocked. fdrop() closes file descriptor when reference count goes to
zero. Close method for vnodes locks the vnode, resulting in "sleepable
after non-sleepable". For pipes, pipe mutex is before kqueue lock,
causing LOR.
