[CRIU] [PATCH 3/7] page-pipe: Don't increase the page_pipe::nr_pipes if we reuse pipes

[Cyrill Gorcunov]

The page-pipe buffers may be reused once queued pages are
dumped, but we happen to increase page_pipe::nr_pipes
all the timer, regardless the fact where page buffer
came from.

In worst scenario this may lead to incorrect -EAGAIN returned
from page_pipe_grow forcing calling code to create new
pipes. This is not critical but should be fixed.

In other words page_pipe::nr_pipes must track _really_
created pipes.
