Revert "b=21760 Application hung in direct I/O"

This reverts commit 91d48dd54d07c3901da34227037a32412243e08a.

With this patch, ptlrpcd sleeps until bulk buffers are unlinked by
the network stack. Meanwhile, no requests/replies are processed
by ptlrpcd which can cause various kind of problems (e.g. eviction).
